These are some kit locks,, I have been looking for ones like these but have yet to find them anywhere..
the brass ones, were I believe shared with me from one of the guys running around with Steve Bookout??
the steel version, my friend Pat Donahue had been working on.. he was finishing it and getting it ready for another guy to build a rifle around.. I don't remember seeing that it had a fly on the tumbler? but looking at the brass one and finding the picture of Pat's work ( with a set trigger near it ) he may have been mod'n it up for them.
Pat, Marlow Westerbeck and I had put on gun/blacksmithing displays at various summer and fall events there for a while. all three are gun bilders and Pat and I do some 'smithing' at the forge.
Pat and Marlow have never met a stranger
and I usually manned the forge, while they showed our rifles and explained Pat's demo sized rifling bench..
