Have a sidelock hammerless here in 10 gauge bearing serial #311XX. There's a good chance this gun is Sauer made - - This is suggested both by appearance and one proof mark that shows a standing male figure holding what seems a long-handled tool with a curved blade at its base. A reference source also suggests the gun was made about 1885, if Sauer made.
There is one extra mark that I would like to understand. It consists of a pair of crossed swords under "S & S" and with a very small and unidentifiable symbol on top of both. This gun bears no proof marks made after the introduction of the German Proofmark Law of 1891.
All help appreciated.
