I'm originally from Ruffsdale, and my Dad knew Worth Sutter (pronounced "Suit-er") in the 1960s and 70s. He was a real "Jed Clampett" kind of a guy who lived out in the sticks, and was an amazingly talented gunsmith, with a client list that reportedly included corporate heads from the Pittsburgh area. He had a small, two-story shop where he plied his trade using a minimum of power equipment. His sons and grandsons worked with him, and they also made custom powder horns to go along with the guns. This lock is a find from a bygone era. I'm pleased to see such interest in this reminder of my boyhood.
I understand that these locks were sold by Dixie Gun Works of Union City, Tennessee, which would have placed them a little closer to Louisiana.
I'd be very interested in getting a copy of that Muzzle Blasts article, if anyone has it in their collection.
Thanks for the memories!
