Original Miquelet flint-lock flintlock. Rare early piece! Medium #2

I know very little about this item, and the only history I have on it is that I bought a few of these locks from an old gunsmith's shop after the old gunsmith passed. The box was marked "Original Miq. Locks" This is number two of two of these I'm listing. Please let me know if you know anything else about these!
