Here is the piece I reported on in my recent thread, "Most Promising Projectile."
I don't have more than a couple of clues as to its origin. Those clues are:
Old lock
Short 27" barrel
Overall length 42"
Weight: 6-7 lbs.
7-groove barrel, 54 caliber. The bore is so pristine I wonder if it is a replaced one.
Heavy brass trimmings.
No markings on metal or wood
Curly maple stock, stained
Note the brass piece set into the lock beneath the nipple/drum.
Look forward to hearing your ideas of what this little musket has for an origin. A home-build is my best guess.
