Repairing a Moores pat. National Arms Derriger

[xtriggerman]

 These little .41RF derringers are pretty neat old guns. This one actually has a decent bore. The gun had a barrel latch button that was completely gone from the barrel latch pin. My task was to fab one up. First thing was to mig weld a new stem onto the latch pin while not taking the hardness out of the pin since the rear of the pin is actually a split spring that has a retaining lip at its tip. Wrapping the bulk of the pin in wet cloth satisfies that need. Here you can see the weld ready for a new button made from a screw head. I only had pictures to determine the size, shape and type/quality of checkering of an original. All in all, it came out pretty nice to where an untrained eye, may not tell its a screw head!
