Hello Ed, I somehow glossed over where you wrote that it was a Bob Roller modified lock. My attention turned to the photos.
Bob I did not mean to offend you, I do have one of your locks on a pistol that I made and the internals are a quantum leap from an L&R lock.
Ed that still doesn't answer my question about the position of the trigger so far back in the trigger guard. Also do you know what the pull weight is?
Again I think it is a handsome pistol.
I have Dyke's book on American flintlock pistols, as well as other books. One thing is clear in those sources, there is greater variety of style and execution than one would imagine.
