Can anybody show a real picture of a Russian assaying mark for gold consisting of the fineness in figures e.g.56 followed by a town mark in an oval frame with or without notches up and down? There is a rather similar silver mark, see P#15 (1882-1898) but I am talking about a gold mark. It has been claimed to me that such a mark exists but I have heavy doubts about that (never seen) ....Therefore a picture would be highly appreciated.
Thank you in advance
