Russ Hamm! That's the first I have heard of him in decades.
I made a bunch of locks on that Maslin plate in years past.
As I recall, his internal parts were pretty much a hopeless case
but externally,it looked good. He had a line of locks all using
one mechanism as I recall. He sold out to another man who
wasn't able to make them work either.I MIGHT still have a frizzen spring
but will have to hunt for it.
