[Qrt.S]

Unfortunately your pictures are not good. I cannot actually understand why there would be a left facing lion in the middle mark, but ? Anyway, my statement is based on what you have written. There was a factory ЗСЧ. It is not 3C4 but Cyrillic 3SCh an abbreviation of 3 (=1973) фабрика Северная Чернь [/b]meaning something like Northern black factory. It was located in Leningrad in USSR. However, is this the case is more pure guessing because the marks are so lousy and in a way "deceptive".

Moreover, there is a narrow possibility that you really have a left facing lion in the middle mark and this 875fineness mark to the right. That would be Estonian marks from 1924-1940. But what is the left mark in that case? The independent Estonia did not use such marks as makers' marks-

My best shot. There might be other explanations...
