Hello everyone.
Do you recognize the hallmarks goldsmith ?
Please, all information.

??? The hallmark's assayer СШ is Sergey Shostak in Moscow 1883-1894 and the maker in the maker's mark looks like ИМ (bad punch). That would be Ivan Mnekin in Moscow 1886-1909. The hallmark shows, anyway, that the object is made at the latest during the first half of 1898.
