    Some attribute such tsuba as belonging to Heianjō or even Yoshirō School, and date them to Momoyama period. I keep this piece under Ōnin rubric, late Muromachi, but this is just a question of personal preference.

    Some inlay is missing, some repaired; traces of rust. Otherwise - decent condition.

    And at Jim Gilbert website: Onin ten zogan tsuba, mid Muromachi. Size: 7.7 cm T x 7.6 cm W x 0.3 cm. Iron plate with brass inlay. Kiku gata. The Ōnin ten zogan style is characterized by the decoration of small brass “nail heads” and wires on a thin iron plate.  The iron often has a soft, granular texture and seems to be prone to rust.  Unfortunately, this rust will undermine the brass inlay and result in the loss of some of the inlay.  This example is in reasonably good but far from perfect condition.  As is often the case, the backside is better preserved, with the wire around the seppa-dai and kozuka-ana, and all petals still intact.
  • Iron tsuba of round form (maru-gata) with 8 openwork petals outlined with brass wire (sen-zōgan) and decorated with brass dots (ten-zōgan), on both sides.

  • Iron tsuba of round form decorated with dragonfly (tombo) and comma (comma-like swirl, tomoe) in openwork (sukashi) outlined with brass wire. The plate decorated with 5 concentric circular rows of brass dots in ten-zōgan. Center of the plate outlined with the inlaid circular brass wire (sen-zōgan). Ōnin school. Unsigned. Mid Muromachi period, middle of the 15th century. Dimensions: Diameter: 89.5 mm, thickness: 3.1 mm. Notes regarding design: "According to various sources, the dragonfly (tombo) is emblematic of martial success, as various names for the insect are homophones for words meaning "victory". The dragonfly is also auspicious because references in the Kojiki and Nihongi link it in both name and shape to the old kingdom of Yamato."  [Merrily Baird. Symbols of Japan. Thematic motifs in art and design. Rizzoli international publications, Inc., 2001, p. 108]. "The dragonfly (tonbo), was also called kachimushi in earlier times, and due to the auspicious literal meaning "victory bug" of the characters of this word it became a popular theme on sword fittings." [Iron tsuba. The works of the exhibition "Kurogane no hana", The Japanese Sword Museum, 2014, p. 13].   Helen C. Gunsaulus' description of the dragonfly emblem is as follows: "This motive, the dragon-fly  (akitsu), is generally accepted as a symbol of the kingdom of Japan, and the origin of the idea is traced to the legend recounted in the Kojiki and Nihongo of the Emperor Jimmu's view of the island from mountain top. He is said to have thought the kingdom looked like a dragon-fly touching its tail with its mouth. From this it received its name Akitsu-shima... etc."  
  • A circular iron tsuba with a design of three monkey toys (kukurizaru) in small openwork (ko-sukashi); the plate further decorated with four rows of brass dot inlay (ten-zogan). The center of the plate and the openings are outlined with brass wire. Copper sekigane. A few dots missing. Muromachi period. Dimensions: 89.0 x 88.2 x 2.9 mm. Kukurizaru was an often used motif on old tsuba. The symbol has two explanations: (1) "upright" monkey, a sort of roly-poly toy, alludes to 'never-ever give up' property of the samurai; (2) monkeys are represented with their hands and feet tied to their back to symbolize self-control. Other examples of the same design:

  • Iron tsuba of round form with brown patina decorated with the design of a Buddhist temple bell (tsurigane) in openwork (sukashi), with details outlined in brass wire (sen-zōgan), the outer ring  decorated with two rows of brass dots (ten-zōgan), and the bell details carved in sukidashi-bori as on kamakura-bori pieces.

    Ōnin school. Unsigned. Late Muromachi period, 16th century. Dimensions: 88.8 x 88.3 x 3.0 mm. As per Merrily Baird, two legends are usually associated with the image of tsurigane, a large, suspended Buddhist bell: one is that of Dojo Temple (Dojo-ji), and the other is of Benkei stealing the tsurigane of Miidera Temple. Interestingly, this type of bell (tsurigane) is not described as a family crest (mon), while suzu and hansho bells are.  
  • Iron tsuba of mokkō form decorated with inome (wild boar's eye) in openwork (sukashi) outlined with brass wire. The plate decorated with 3 concentric circular rows of brass dots in ten-zōgan.

  • Rose quartz snuff bottle of rounded rectangular form on raised foot with round neck, carved in relief with a double dragon in a cartouche; round turquoise stopper with silver collar.
    The Eastern dragon is not the gruesome monster of medieval imagination, but the genius of strength and goodness. He is the spirit of change, therefore of life itself. Hidden in the caverns of inaccessible mountains, or coiled in the unfathomed depth of the sea, he awaits the time when he slowly rouses himself into activity. He unfolds himself in the storm clouds; he washes his mane in the blackness of the seething whirlpools. His claws are in the fork of the lightning, his scales begin to glisten in the bark of rain-swept pine trees. His voice is heard in the hurricane, which, scattering the withered leaves of the forest, a dragon quickens a new spring [C. A. S. Williams. Chinese Symbolism and Art Motifs / 3rd Revised Edition. — Rutland, Vermont & Tokyo, Japan: Charles E. Tuttle Company, 1993].

  • Tsuba of chrysanthemoid form (kikka-gata) with yamagane core and woven copper wire pattern. Copper sekigane. Shingen school. Height: 70.2 mm; Width 67.2 mm; Thickness at seppa-dai: 3.4-3.6 mm, overall 7.3 mm. Weight 82.7 g Inscription on the wooden box reads: "Muromachi period Mumei Zōgan Shingen Tsuba" Muromachi period, 16th century. Age attribution is based on the fact that the core is made of yamagane; later copies of Edo period are usually made of iron. This small and light tsuba was likely mounted on a combat sword, while larger and much heavier woven wire Shingen tsuba of Edo period were of purely decorative purpose. http://varshavskycollection.com/shingen-tsuba/
  • Iron tsuba of six-lobed (mutsu-mokkō-gata) form, with six wild boar's eye shape (inome) openings (sukashi). Ryo-Hitsu and the entire perimeter of tsuba have typical for this school raised rim; raised seppa dai. Lobes are decorated in low relief carving (sukidashi-bori). On the obverse: chrysanthemum, Genji mon, waves and rocks, grasses and star, bellflower, star and flower in tortoiseshell (kikko). On the reverse: Stars and different flowers, and flying geese.  The plate is damaged to the left of nakago-ana and around the left hitsu-ana. Kamakura-bori school. Late Muromachi period (1514-1573). Diameter: 89 mm; Thickness at seppa-dai: 4.0 mm; Weight: 108.8 g [large]. There is a similar tsuba in this collection, TSU-0345.2018, but with a different motif and much smaller: diameter 74.3 mm, thickness at seppa-dai: 3.2 mm, weight: 62.8 g.

      Another look-a-like tsuba can be found at the Compton Collection, part II, pp. 14-15, №17, though his tsuba is more massive (80 x 84 x 4 mm).

    Compton Collection, part II, pp. 14-15, №17: Kamakura-bori tsuba, ca. 1450.

    This tsuba, TSU-0401.2019, is the biggest of all three (another mine and the one from Campton Collection). The presence of a flower in a tortoiseshell symbol (crest or mon) on this tsuba alludes to Izumo Shrine. The overall piece, with symbols of grasses, waves, flowers, incense, stars, and flying geese, is full of autumnal connotations.  
  • Small amber-glazed marbled (Jiaotai) pottery tripod censer. Inside the glaze is monochrome because the clay itself is not marbled. Spur marks on the bottom. Small chip on a lip. China, Henan province, the Tang dynasty [唐朝] (618 – 907). Diameter: 6.3 cm; Height: 5.5 cm.
  • Snuff bottle made of smoky quartz with white skin carved with cats hunting butterflies design; cherry quartz stopper. Late 19th century. Dimensions: H70 x W36 x D17 mm
  • A very large and very thin iron tsuba of round form decorated with design of formalized butterfly and dragonfly in openwork (sukashi). The characteristics of the plate resemble those of Kamakura period ko-tōshō tsuba. However, the design seems too 'modern' to me, but it's hard to tell; it may be a late Muromachi or Momoyama period work. Tōshō or Ko-Tōshō school (or a Katchushi). Muromachi period. However, Boris Markhasin and Skip Holbrook insist this is a 20th-century machine-made tsuba. Dimensions: 99.6 x 100.5 x 2.1 mm. This is what Jim Gilbert says about old tsuba:
    "Traditionally the old iron plate tsuba are classified into Ko Tosho (old sword smith), and Ko Katchushi (old armor maker) styles. It is sometimes difficult to justify attribution of a given tsuba to the Tosho or Katchushi category. Generally guards with raised rims or relatively complex designs tend to be assigned to Katchushi. This is basically a convention we follow out of habit and convenience." [...] "In Token Kai-Shi part six, Articles by Akiyama Kyusaku, Robert Haynes comments: "…from 1300 to 1400 over 150,000 MOUNTED swords were made in Japan for export alone. This means that over four tsuba a day were made for 100 years. This would mean that at least 3000 persons were making nothing but tsuba, let alone all the other fittings needed to complete these swords. With sword smiths, fittings makers and all the other artists need to complete a sword for export, at least 10,000 sword artists were working together, in any one of these hundred years."
    Another tsuba of similar design, Tōshō school, is illustrated in this collection; see TSU-0319.2015. Reference to this design can be found in LIB-1359.2017 Japanese Swords and Tsuba from the Professor A. Z. Freeman and the Phyllis Sharpe Memorial collections, Sotheby's, London, Thursday 10 April 1997; p. 18-19, lot № 37: "A Kamakura-bori Tsuba, Momoyama Period. ...pierced with two large formalised butterflies..."

  • Iron tsuba of round form decorated with design of dragonfly in negative openwork (in-sukashi). It may be Ko-Tōshō (old Tōshō) or just Tōshō school, without a 'Ko'. Probably the dragonfly here is used as a family crest (mon). Muromachi period. However, Boris Markhasin and Skip Holbrook insist this is a 20th-century machine-made tsuba. Dimensions: Height: 95.0 mm. Width: 93.6 mm. Rim thickness: 2.1 mm. Center thickness: 2.3 mm. Nakago-ana: height = 30 mm, width = 7.8 mm. A dragonfly design is described by John W. Dower as following "During the period of feudal warfare, the dragonfly is reputed to have been am especially popular design applied to arrow quivers, and some warriors adopted it as a family crest. One reason for this was the insect's alternative names of katsu mushi and shogun mushi, both meaning 'victory insect'." Merrily Baird is even more talkative regarding the matter: "The dragonfly (tombo) in Japan is emblematic of martial success, as various names for the insect are homophones for words meaning "victory". The dragonfly is also auspicious because references in the Kojiki and Nihongi link it in both name and shape to the old kingdom of Yamato. This legacy has led to the use of dragonfly as an emblem on arrow quivers and as family crest. It also appears occasionally in conjunction with such imperial motifs as the chrysanthemum. Used in a context devoid of historical associations, the dragonfly is a seasonal symbol of late summer and early autumn." Dragonfly was an extremely often motif for the tsuba in all times, primarily in earlier times, before Tokugawa pacified the nation. The same motif is used on Ōnin tsuba in this collection:
  • Round tsuba of iron; well forged thin plate decorated with a rudder (kaji) and an oar, or paddle (kai) with a water drop, executed in a combination of negative (in-sukashi) and positive (ji-sukashi) openwork. It may be Ko-Tōshō (old Tōshō) or just Tōshō school, without a 'Ko'. The characteristics of the plate point toward an older piece, however the combination of negative and positive silhouettes pulls the date of manufacture in an opposite direction. Muromachi period. Height: 90.0 mm. Width: 89.0 mm. Rim thickness: 2.1 mm. Center thickness: 2.3 mm. Nakago-ana: height = 29 mm, width = 8.8 mm. A rudder and an oar design is classified by John W. Dower as "Sailing vessels and gear": "Unlike many other motifs, sailing vessels and sailing gear failed to collect an interesting lore or to develop levels of meaning." Merrily Baird does not say anything about these symbols. Yuzuri Okada says: "Ships, sails, rudders, etc. also supply motive of the same class as wheels." He does not provide us with the description of the motive supplied by the wheel. The same motif is used on Ōnin tsuba in this collection:
  • Iron tsuba of round form decorated with design of sea waves in low relief carving (kebori) and pierced with design of cherry blossom in negative silhouette (in-sukashi) and water wheel in positive silhouette (ji-sukashi). The solid portion of the plate has a shallow groove just before the edge. Copper sekigane. School attribution is unclear. Unsigned. Momoyama period, 16th - 17th century. Dimensions: Height: 70.3 mm, width: 71.1 mm, thickness at seppa-dai: 4.4 mm, at rim 4.1 mm. Provenance: Robert E. Haynes, Mark Weisman. This is what shibuiswords.com says about this tsuba:
    "A very unusual iron plate tsuba. The solid plate is carved with waves on both sides. A cherry bloom in sukashi, lower left, and the right third of the plate in openwork with design of a water wheel. The rim with some iron bones. The hitsu-ana is original but the shape may have been slightly changed. One would expect this to be the work of the early Edo period, but the age of the walls of the sukashi would suggest that this is a work of the middle Muromachi period. This must be the forerunner for the Edo examples we see of this type of design." (Haynes)
    I managed to find a look-a-like tsuba in Haynes Catalog #5, 1983, pp. 20-21, №44: "Typical later Heianjo brass inlay example. Ca. 1725. Ht. 7 cm., Th. 4.5 mm., $100/200".

    Haynes Catalog #5, 1983, pp. 20-21, №44.

    We see that the  plate design of both tsuba is the same, and the only difference is the trim. It would be logical to assume that both pieces were made at about the same time, rather than 225 years apart. To be fair, let's accept that they were made in Momoyama period.
