What do you folks think? Pretty gouged up. Took a bastard file to it just to see and while it didn't really "bite", it didn't skate either and left a nice shiny ring showing the frizzen is cupped in the center. No, it does not spark well. 2/3 of the time it doesn't spark at all regardless of freshness or positioning of flint. Repairable? Or time to replace? If replacing I need an ID on this lock so I can get one that'll fit and work. It's 5/8 wide, roller on the spring. Thanks.
