Availability of hammer gun lock parts
 

Folks, I'm looking at an early-1880s Parker hammer gun that has some missing or broken parts on the right lock, and other issues. Check this one out on GB: 258121627. Mismatched frame and barrels, with some additional stampings on the barrel. Any opinions on this? A factory mating? The sellers says it's reasonably tight and on face, with the lever centered when closed.

How hard would it be to find parts for the lock?

I'm looking for a restoration project gun in a larger frame (3 or larger). As in, puttering-around project, not for profit!

Thanks!

Parker hammergun locks show up on Ebay from time to time. Some are complete....some not.

Yeah, I have seen them from time to time. rarely individual parts, but usually as complete locks or pairs. I would think you would find one in time. Or maybe a new spring could be made by the right person.
Doesn't look like a bad gun. If I didnt just pick up my lifter restoration project, you might have had some friendly competition from me on this one.
