Bottom left to right; French Minerva head with the number (2) under its chin for fineness 800/1000, I believe it to be for Paris, unknown mark to me(St. Petersburg?) and followed by a French makers’ mark (C- CC C-D with an apple in the middle) in a lozenge.
Forget Russia and St. Petersburg. The mid mark is not a Russian mark. The Minerva head is a French mark actually Paris 1838-1973 as also indicated by Oel. Sorry but the maker is unknown to me.
