I have a medal which my father won in a gym contest in 1912. I say medal, but it is actually of the sort intended for attachment to a watch chain such as were worn then. (Is there a proper term for such items?)
On the back is this set of marks, which I don't think are silver marks, but I wonder if anyone can please give me any information as to any meaning they may have. Presumably the initials are those of the maker?
