lately I promised to show some Fabergé in details and how he marked in reality - we mostly see only fakes and think his mark is minimum several centimetres large. The contrary is the case.
Karl Fabergé used the products of several other firms for his work - Fedor Rückert was one of them.
Photoframe, enamel clausonné, 88 Zolotniki, no assay mark(!), made by F. Rückert, bought 1913 in Odessa




Triangular bowl, enamel clausonné, 88 Zolotniki, made by F. Rückert, bought 1913 in Odessa, assay mark Moscow (!)1908-17(26)



Match safe in the English pattern, enamel clausonné, 88 Zolotniki, made by F. Rückert, bought 1913 in Odessa, assay mark Moscow(!) 1908-17(26)



Please notice the very small (mm)marks but clear letters!
Regards
Zolotnik
