Kamakura-bori school. Late Muromachi period (1514-1573). Height: 64.2 mm, width: 74.3 mm, Thickness at seppa-dai: 3.2 mm, at rim 2.6 mm. Weight: 62.8 g (light). NBTHK old green certificate №561: Tokubetsu Kicho  - "Extraordinary Work". A 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). NBTHK paper says that the motif is Hakkei (八景), i.e. "Eight Views," so several interpretations are possible (the original Chinese ones, Omi Hakkei, etc.).  However, most likely it is the 'Eight views of Omi' (近江八景  - 'Omi Hakkei'). Why the artist selected a 6-lobed form for depicting 8 views remains unclear, and thus we are in our right to raise the question whether the motif is indeed Hakkei. The term Omi hakkei (eight views of Omi) refers to painting or print sets which illustrate life on the shores of Lake Biwa in Omi (now Shiga Prefecture). The model for such paintings came from China, where, from the eleventh century onward, painters had produced eight views of the Hsiao and Hsiang lake areas of Hunan Province. The themes, which follow the original Chinese models, are: geese descending to land, returning fishing boats, clearing rain, a snow-covered evening landscape, the autumn moon, night rain, a temple bell at evening, and the glow of sunset. Japanese artists have also used the eight-theme approach for other parts of country - including cities - and applied it to subject matter other than landscapes. [Merrily Baird. Symbols of Japan. Thematic motifs in art and design. Rizzoli international publications, Inc., 2001, page 308-9]. Japan Encyclopedia by Louis Frédéric also mentions Omi Hakkei as "Eight landscapes of Omi", and states that this theme was often cited in poetry after 1500. It is likely that the tsuba in focus is designed under the influence of the theme popularity in the 16th century. The theme was effectively exploited by prominent ukiyo-e artists Suzuki Harunobu and Utagawa Hiroshige in the 18th and 19th century, respectively. These are the eight scenes of the theme (see Wikipedia):

• Returning sails at Yabase (矢橋の帰帆) - Yabase. Yabase is an old harbour on the east side of the lake. Near the Tokaido, it was used for a shortcut to Otsu by boat.
• Evening glow at Seta (勢多（瀬田）の夕照) - The Chinese Bridge at Seta. The long bridge across the Seta was used by the Tokaido. In the background the "Fuji of Omi", the Mikamiyama. It is just above 400 m, but indeed well visible.
• Autumn moon at Ishiyama (石山の秋月) - Ishiyama Temple. The Ishiyamadera was located on a hillside next to the Seta River. It got his name form the strange rocks on which it is built, partly on supporting beams. A hut at the upper end of the site allows a view of the lake, and the moon.
• Clear breeze at Awazu (粟津の晴嵐) - Awazuhara. Awazu is well known for its pine wood, Awazu-ga-hara.
• Evening bell at Miidera (三井晩鐘) - Mii-dera. Miidera temple was built in the 8th century. Its famous bell is one of the "Three bells of Japan", the other two being those at Byoodo-in, Uji and at Jingoji, Kyoto.
• Evening rain at Karasaki (唐崎の夜雨) - Karasaki Shrine. Karasaki is a small cape with a single large pine tree, a hitsu-matsu.
• Wild geese returning home at Katata (堅田の落雁) - Ukimido. Alighting geese cannot be seen always, however the little temple near Katata in the square hōkyō-style, detached from the lakeside, connected by a bridge. The first part of the name uki is the same as in Ukiyo-e, meaning floating. Midō means temple.
• Evening snow at Hira (比良の暮雪) - Hira Mountains. The Hira mountains on the west side of the lake experience the hard winter, when the winter monsoon brings much snow from the continent.

In any case, as a conservative, I say that it is a landscape motif and a late Muromachi period work, rather than Omi hakkei motif and a mid-Muromachi work.

Iron tsuba of almost round form with a brass outlined circular opening (sukashi) in the bottom adorned with the Myriad Treasures [takaramono, 宝物] and winter motifs inlaid in cast brass (suemon-zōgan); hitsu-ana possibly cut later, both plugged with shakudo, nakaga-ana fitted with copper sekigane. According to Merrily Baird^*) (2001), the symbolism of Myriad Treasures “is associated with the Seven Gods of Good Luck, who carry them in a sack”. Among the treasures, which are said to ensure prosperity, long life, and general good fortunes, are (reading clockwise from the top):

1. Sake set [shuki, 酒器], namely flask, ladle, and cups
2. Cloves [choji, 丁子]
3. Purse of inexhaustible reaches [kinchaku, 巾着]
4. Magic mallet [kozuchi, 小槌]
5. Key to the storehouse of the Gods [kagi, 鍵]

Then, Pine, Moon, and Bamboo (see below);

7. Rhombus, or Lozenge (hosho, 方勝), with the second ideograph meaning victory.
8. Sacred (or wish-granting) gem, or jewel [hōju, 宝珠]
9. Hats of invisibility [kakuregasa, 隠れ笠]

The Myriad Treasures is carried by the Seven Gods of Good Luck (a.k.a. the Seven Lucky Gods or Seven Gods of Fortune [shichifukujin, 七福神], who are transported by the Treasure Ship [takarabune, 宝船] during the first three days of the New Year. Pine, Moon, and Bamboo: bamboo [take, 竹] and pinecones [matsukasa, 松笠], or pine [matsu, 松] – two of the Three Friends of Winter [shōchikubai, 松竹梅] – symbolize fidelity, fortitude, steadfastness, perseverance, and resilience. The third ‘friend’  – plum, [ume, 梅] – in this case replaced by the Moon [tsuki, 月] – large (11 mm) circular opening at 6 o’clock; the three small carved dots represent the dewdrops. The other side is decorated with an arabesque (karakusa) of cloves and vines, with carved dots (dewdrops) along the rim. The overall New Year / Winter connotation of the tsuba is clear. The prominence of the Moon conveys purity, coldness (sadness/loneliness), and slenderness – the inherent qualities of a samurai. H: 93 mm x W: 90 mm, thickness 4.2 mm at the centre, slightly tapered towards the rim. *) Merrily Baird.

Two ymagane tsuba (daisho) with chiseled diaper pattern of waves. The larger tsuba (dai) is of mokkō form with a wide (4.6 mm) polished rim (fukurin?). Water spray is realized in copper ten-zōgan. Size: 75.0 x 71.6  x 3.2 (center), 4.0 (rim) mm. Copper sekigane. The smaller tsuba (sho) is of oval form, without a rim. No inlay. Size: 53.2 x 45.5 x 4.1 mm. Ko-kinko school. Muromachi period. In Kokusai Tosogu Kai; 5th International Convention & Exhibition, 2009 on page 51 under № 5-U8 there is a piece from George Gaucys collection, described as follows: Unsigned Tachi-Kanagushi tsuba, Yamagane base. Nami (wave) motif. Circa: Muromachi period (15th century). 6.88 x 6.81 x 0.45 (rim), 0.36 (center). The classic wave form is typically seen in Muromachi period tosogu. The patina is rich and rustic, which presents history and warmth. This tsuba may be interpreted as either tachi-kanagushi or ko-kinko work. Early tachi tsuba were symmetrical in design and also not very sophisticated, Design elements filled in up to seppadai as the waves do in this tsuba. There is a simple fikurin of the same metal and it is flat to the plate. On the ko-kinko side, the crests of the waves show more complexity than tachi works and less symmetry. A very intriguing tsuba from late Muromachi period."

Iron tsuba of quatrefoil form (mokka-gata) adorned with the design of stars, wild geese, blossoms, leaves and tendrils realized in the brass inlay. The inlay technique includes suemon-zōgan and ten-zōgan. A smaller opening (kozuka hitsu-ana) surrounded by a scalloped brass border. The seppa-dai bordered with linear inlay. A few dots of inlay on both sides are missing. Measurements: height 71 mm, width 70 mm, thickness at centre 2.7 cm Time: Late Muromachi (1514 – 1573)
