One of the world's earliest known wheel-lock mechanisms, ca. 1535-40

Michael,
Very interesting lock.
I have not seen a sear/trigger that works quite like this one. very simple, but foolproof as well!
If I ever "get 'round" to making a wheellock, this is something to try!
(Been thinking about it forever, but something always gets in the way..)

Thanks for posting the pics.

Richard.
