While in Glasgow, I also learned of three Chinese silver ingots in the collection of The Hunterian. The ingots can be viewed online – with several images per ingot – on The Hunterian website:
10-ounce local tax ingot, of Luzhou (瀘州), in southeast Sichuan, 1908/9 (宣統元年) , cast by Smith ZHANG Hengyi (匠張恒益) [reading of name uncertain]. Compare: Cribb 435 (Joe Cribb, A Catalogue of Sycee in the British Museum, 1992, p. 171, no. 435). Cribb type XL (Sichuan certified ingot 四川票錠)
Ten-ounce ingot, of Baoshan county 保山县, in Yunnan. Could this be a Ming dynasty ingot? (Compare Lot: 1218 明代云南“保山县 罗石林”十两螺纹锭一枚, sold at auction, by Beijing Cheng Xuan 北京诚轩, Beijing, 8 Nov 2008, http://data.shouxi.com/item.php?id=36582)
One-ounce(?) ingot, of the Shanxi small ingot type 山西小宝. (Cribb type XXIV or XXV). The inscription reads 喜喜 (double happiness).
Many thanks to Joe Cribb for checking these IDs. His A Catalogue of Sycee in the British Museum (1992) was the first major work on Chinese silver ingots in English (perhaps any Western language?).
Also in Glasgow is Dr Adrien von Ferscht, Honorary Research Fellow at the University of Glasgow, and specialist in Chinese export silver. See his website Chinese export silver (中国进出口银) – a wealth of information.
