Superimposed firearms

[Matchlock]

I would like to add that the inside of the first detached wheellock mechanism posted by Marcus in this thread is for a ca. 1630 North Italian two-shot superimposed-load military carbine on the Bossi system.

I attached images of a Bossi carbine, formerly in the W. Keith Neal colln., from a Czerny's sales catalogue, and of three other superimposed-load wheellock guns from the W. Keith Neal colln., Christie's. Please mind that the flintlock musket, French, ca. 1640, obviously has severe working problems in both its locks as the cocks are not in the correct upright position for half-cock but they lean forward too much so that each flint actually touches the steel instead of standing clear off it!


Best,
Michael
