Hello,
My friend Hans Muller gave me an old lock in parts.
I made 2 bolts and a case for the sear and a new bridle.
The lock is 5 inch long.
Jim Chambers sells a 5 inch lock on his site for pistols.
I made the choice to make a pistol for the lock.
Last weekend I made for the first time a full scale barrel for the old lock.
It is a swamped barrel, caliber 60.
Thanks Rolf for your explanation.
Later more.
