I have a question regarding German guns from this period. Apart from varying degrees of engraving and some slight differences in receiver shape or cocking indicators, the boxlock guns appear to originate from the same basic design. Did gun makers like Sauer, Merkel, Kerner, etc all source them from the same factory and finish them to their own specifics, or did they just all use the exact same design? Correct me if I am wrong, but Simsons appear to be slightly different. My T+S Nimrod is clearly a completely different action.
