Never saw a parlor gun, but back in the 1950's I worked in a gas station where we had a target set up on a door in a back room. Had about a 20' long range. The owner and other attendant and I would practice using 22 shorts. We pulled the bullets, dumped the powder and reseated the bullet. It left a lot of dents in the door but never penetrated.
Find a local welding shop with a laser welder. Even some jewelry shops have them.
They can lay down a very small bead to build up the worn areas that you can easily file off by hand.
Now I don't know that I'd really classify it as a parlor gun. I think a "garden gun" would be a more apt description. .
Well so far I've only shot the bolt action on my deck, so I guess it's a deck gun?
Had this gun rack in my closet for years, but never put it up. Finally found a use for it, since the bottom gun doesn't shoot, and the top one is cheap. I've got another one coming that will look more like the bottom one this week sometime, so I'll probably swap it out for the bolt action.
Very nice, you need now to add a couple of appropriate critter head mounts for those guns..
You know that barrel sure is mighty thick considering how powerful that round is..
Problem is, I think I'd need a gunsmith that's familiar with this type of fire control group (which is why I think maybe one that specializes in flintlocks or percussion rifles might be a good choice) to identify exactly what the "weak link" is. And I don't want to dump 3 or 400 bucks into a 200 dollar "novelty" rifle.
Made to be rebored to the next bigger Flobert round when needed. These guns tended to have a hard life - corrosive priming and not cleaned often, if at all. Barrel was the most expensive part of the gun, so was reused when possible.
I would take it to Jim Fishel in Gosport. He works on old stuff like this. His work is also reasonably priced and he will give you a price before he starts work. Just a wild guess, but you may be able to get this fixed for less than $100. There is not much to these guns. He will have to make parts and fit them because, like Indy said, they were hand made by a bunch of different little shops. Probably needs a trigger return spring and some work on the sear engagement surfaces.
