Raimey, yes it's hard to pigeonhole the designs. There are lots of patents for "non Sidelocks" that came after the flintlock, percussion, pinfire, and more, which used the sidelock design by default. Was it 1876 for A and D ? Really just a "non Sidelock". But maybe it was the most important invention in gunmaking that we can point out. Following in no particular order in the U.S. were boxlocks from Davis, Ithaca, Baker, Parker, Colt, and several others. Some even proved in court not to be an A and D. In Britain we had , proved in court, Greener not to be an A and D infringement. Then there's the sideplated guns like Lefever, Tobin, etc that fit neither sidelock or boxlock.
