Having lived in Bedford County, when I was ready to build my first Bedford style rifle (1975) it was the only "ready made" Bedford lock that, IMHO, I thought looked like a real Bedford lock and being a member of the Shawnee Rangers, the local ML shooting club, it presented me with the opportunity to see a large number of originals. On that first rifle I used a Hamm percussion lock, I still shoot that rifle, and after 39 years it has never let me down.
My next rifle was a flintlock Bedford, of which I don't think many original rifles have been documented. On this gun I used a Doc Haddaway lock, and my luck is still holding out . I didn't get to Friendship until the early '80s and with no internet I kind of lived in a "bubble", so I was unaware of things that did not show up in DGW catalog.
I guess I got caught up in OLD THOUGHTS. I think the Hamm percussion was worth what I paid for it. BPRICHARD
