Ken61:

Maybe a bit off track, but the above is a Charles Daly badged hammergun wearing a number of 836 and the only marks given were the tubeset knitter CK. So a S,D&G badged and evidently didn't pass thru H.A. Lindner's hands but maybe Georg??

On the 1890 date, to be convinced otherwise, all I would need to see is a 2nd series wearing an inverted APUN on the standing breech. Payment of royalty & application of APUNs @ a satellite stamping station would have dropped off mid 1889. 1st serialization sequences mimics patent protection period for the A&D Body Action. More on the calculus later....

Cheers,
