I don’t know the origin of the lock. I know John did some casting, but I don’t know if he did locks. He did some of the matchlocks used at the Jamestown-Yorktown museums, and a number for reenactors in the US. I also have a pistol he did.Hi Tom
Thanks so much for your reply and the cool photos. That gun looks so pre-1700. Really like it. So I take it the lock was a custom - one-off ? Again, super neat gun. Thanks for posting.
In addition, I ran across this pic years ago, watermarked Life (Magazine).
