Don't mean to interupt your personal discussion

but am i right to assume that the developement of butstocks was gradually? From the dagger grip of the early 1510-30 the fishtale butstock of 1530ish to 1560ish and the pommel variation like those on the trabanter leibgart (like those of Augustus I, earliest know of those is 1586, last year of Augustus his reign)
I also found a few pictures like this (presumably) Dutch wheel lock with Spanish barrel.
The detached lock as discribed by Michael
A pistol with first signs of a rounded nob/pommel (?), gilded and decorated with plaques of ivory
I will look up the books etc later
