Lock ID help

[axesbold]

Does anyone know the maker of this lock? It needs a frizzen, if not complete replacement. At some point someone has taken a file to it. It's very unreliable I'd like to get as close a replacement as possible. I don't know the maker of the pistol. It was purchased in the early 90s at a gun show in Knoxville. It has lightly etched in the barrel ?C? PM., which might be a previous owner. Thanks!

The lock has kind of a CVA look to it.

It's a Jukar, they came from the factory unreliable so not sure if replacing anything would help.

Looks like enough metal left it could be resurfaced to look better, but that would mean heat treating process(?). Did someone run a hacksaw blade through the ball (flint tightening screw) or is that the way it was made?

Thanks for the replies guys.
Bubba I have a couple of CVA percussion guns and the rifle lock plate is very close to this lock. Might see if I can find an old CVA lock and it might fit.
Patch thanks. I googled the Jukars and didn't find one quite like this. The grip is different, and I didn't see any without a ramrod. I think the stock is maple, as opposed to beech or whatever the spanish guns used. The barrel is browned. Of course it could be a reworked Jukar. The barrel looks good with nice rifling so I think it would be a good shooter if I can get it reliable.
Davey I have thought about refacing the frizzen. I was wondering if I could find a replacement. I've seen them for around twenty bucks. Just not sure if they'll fit. The slot in the ball looks too good to be done by hand with a hacksaw, but I really don't know. This is how it came to.me.
