Sotheby's, London, Thursday 10 April 1997, page 22, item 60, saying that this is a "Kyo-sukashi tsuba, early to middle Edo period (late 17th/18th century) [Sotheby's attribution], and that it represents "a small bird among omodaka and aoi plants".

The use of Musashino themes was particularly common in the Momoyama and Edo periods". Pampas grass with dew drops and wild geese in flight collectively provide strong autumnal connotation.

    Merrily Baird in her book "Symbols of Japan" [Merrily Baird. Symbols of Japan. Thematic motifs in art and design. Rizzoli international publications, Inc., 2001] provides the following explanation of the Wheel-of-the-Law symbol: "The Wheel-of-the-Law or Golden Wheel (rimbo, kinrin) has its origins in India, where it is known as chakra. [...] In Buddhist practice, it has been represented with eight spokes, reflecting the eight-fold path to overcoming worldly desire, and it signifies that all illusions will be crushed by the faith's enlightenment. [...] The Wheel-of-the-Law is an attribute of such deities as Senju Kannon, the Thousand-Armed Kannon, and Dainichi Nyorai, the all-illuminating solar figure who is the principal deity for Shingon Buddhism. From the Edo period on, the wheel also has been used in a secular manner", e.g. on family crests.

Rim thickness: 5.5 mm. Center thickness: 6.6 mm. Provenance: Sasano Masayuki Collection, № 222: "It is believed that sparrows nest in a bamboo grove". According to Merrily Baird [Merrily Baird. Symbols of Japan. Thematic motifs in art and design. Rizzoli international publications, Inc., 2001], "a bamboo grove is said to be emblematic of security as the bamboo is resilient even in the face of high winds and heavy rains. [...]  The association of the sparrow (suzume) with bamboo is an old one found in Japanese poetry, paining, and design. The bird is said to be obsessed with its honor, especially the repaying of debts".  
  • Iron tsuba of oval form with design of iris and plank bridge (yatsubashi) in openwork (sukashi). Rounded cornered rim. Unsigned. Attributed to Jingo - 3rd generation Shimizu, 2nd generation Jingo (1691-1777) [M. Sesko, Genealogy..., p. 94]. Edo period: Late 18th century (Hohreki Meiwa era). Height: 69.5 mm. Width: 65.2 mm. Rim thickness: 4.6 mm. Center thickness: 4.8 mm. Provenance: Sasano Masayuki Collection, № 251: "Shimizu. Third generation Jingo (died at 87 years of age in the sixth year of An-ei, 1777). The eight-section bridge with irises are arranged to create the design of 'yatsubashi'. The features are unique for the Shimizu school and show no influence of the Hirita, Nishigaki or Hayashi schools". The design visually resembles a butterfly. As described in Family Crests of Japan by Stone Bridge Press [Family Crests of Japan; Stone Bridge Press, Berkeley, CA, 2007], and also in Japanese Family  Crests by Yuzuru Okada [Yuzuru Okada. Japanese Family Crests // Series: Tourist Library: 37. Board of tourist industry; Japanese Government Railways, - 1941], there is a special technique used in construction of family crests, called 'reshaping' by the former and 'reconstruction' by the latter: "reconstruction is realized when a motive has its general shape composed of the detail of entirely different motive as, for instance, the crest of a butterfly formed of pine-needles. [...] The fanciful and ingenious forms evolved in this way may be represented by the kasiwa-giri or 'oak-leaf-paulownia', the ogi-bisi or 'fan-lozenge', the matuba-zuru or 'pine-needle-crane', the omodaka-kotyo or 'water-plantain-butterfly', etc." In our case we can call the motif yatsubashi-chocho or 'Iris-and-Bridge—Butterfly'.

Center thickness: 5.0 mm. Provenance: Sasano Masayuki Collection, № 264: "Nishigaki. Third generation Kanshiro (died in in the eleventh year of Hohreki, 1761 at the age of eighty-two). This oblong shape appears a little amateurish at first, however, it was done intentionally to add flavor to to the design. The neat composition is a feature of the third Kanshiro."

Hitsu-ana outlined with inlay of brass wire. Surface treated with lacquer. Copper sekigane. Though some consider this type of tsuba to resemble Heianjo school, “...the brass trim around the hitsu-ana is a characteristics of Ōnin work” [Japanese sword guards. Onin – Heianjo – Yoshiro. Gary D. Murtha. GDM Publications, 2016; p. 27.]. The Ōnin origin is reinforced by scattered ten-zōgan elements here and there through the plate. It is possible that the tsuba was initially of round form and later trimmed to mokko shape. Mid Muromachi period; 15th century. Dimensions: Height: 87.2 mm; Width: 87.9 mm; Thickness at seppa-dai: 3.6 mm.

Brass inlays represent flowers, branches and leaves, as well as halved plum blossom, halved chrysanthemum blossom, cloud, and chrysanthemum-on-water symbol - the mon of Kusunoki Masashige. Abundance of family crests of so many powerful warrior clans symbolizes heritage. "The brass trim around the kozuka hitsu-ana andd the seppa-dai are characteristics of Onin work" [Japanese sword guards. Onin - Heianjo - Yoshiro. Gary D. Murtha. GDM Publications, 2016; p. 27.]
