Need help with schematic for single shot swivel barrel cap n ball derringer

[A34]

Hey Guys!

I recently picked this single shot cap and ball swivel barrel derringer up as a bag of parts. It is a cap n ball, not rimfire. I'm hoping someone can give me information on who might have made it, the schematic or instructions for it, so I can see what parts I'm missing.

I don't know if it's a kit gun or who made it, but I think it might be a kit gun. The pics show alot of parts that aren't for the derringer. I'm not sure what's missing or how it all goes together, so would appreciate any help! Thanks!

On the bright side, I have alot of revolver parts, I might go into the parts biz. LOL.

UPDATE: I added some additional pics. The bore diameter ranges from .429 to .436 per my cheapo harbor freight digital caliper. Pictured is a .424 ball that seems a tight fit, but could probably be rammed home.

I see two to three parts that belong to a modern revolver (maybe even a single action). On the left is a hammer spring. Just below the grip frame is a cylinder paw. And just below the trigger is a cylinder bolt. Not for the pictured gun.

That's about all I can do for you. Good luck.

Noticed one more that belongs to a single action revolver. The three forked leaf springs in the upper left are for the trigger and cylinder bolt.

Oh yeah...And the nipple wrench in the upper center.

I can't see a trigger so that's something you have to get or make. And a trigger spring.

The grip scales could be the right ones, if you haven't got any screws that will work, rethread the frame. Don't waste time looking for "correct" screws.

This looks like a rimfire to me.
cap n' ball would have the nipple on top of the barrel for the absolute majority of such guns and the barrel would not be detachable in that way.

To me it looks like your supposed to release a screw on the bottom and slide the barrel forward and swing it too the side.

No breach loading CnB would load that way.

Check the breach end of the barrel and see if there is a smooth 1/4" -ish hole with a larger recess at the end.

It's probably 22 Long

Thanks for the info Sir! This is actually a cap n ball. I've attached a pic of the threads in the barrel and where I partially installed the cone to be sure it would thread. It's kinda weird. In these pics, I cleaned the barrel up, and rubbed some bluing paste on it. I might do another round of that, but want it to look aged, not new.

So it is!
I've never seen one like that before, but then I collect old guns.

What caliber is it?
I'd lay a wager that there's a rimfire version of this model or even a small caliber centerfire. The construction seems to be cartridge based.

 

[Ryden]

The trigger shouldn't be too hard to make, but i'd recommend that you get knowledgeable help for that, trigger geometry and safety are very much intertwined.


Possibly the small part directly underneath the cones in the first picture might be the trigger. It has sort of the right shape.

Apparently, that's a swivel barrel vest pocket derringer.

By the looks of it, the shiny thing directly under the trigger hump in your picture might be the trigger, only it's up side down



Now, put it together as much as you can and see what needs to be fixed

I added a pic of a .424 ball in the barrel. It fit kinda snug. I'm not sure if it would have used a patch?

Thanks for posting that! It sure does look really close. This one doesn't have a ramrod (or whatever part Q is) but that schematic should help me alot!

 

[Ryden]

Great!
You're really close now, could you post a pic of the bottom of the barrel?

The schematic shows a spring loaded detent that your gun doesn't have, but there's some extra holes in your frame that could be for something similar.

If the ball is snug as in could easily be pushed inside the barrel, then a patch of thin ticking might be good.
If it's snug as in could be pushed in the barrel with 5-10# of pressure then skip the patch.

Part Q had me stumped as well, it's probably cosmetic.

"Cones"? How 'bout "nipples".

 

[Ryden]

Cones are archaic but perfectly understandable, might be British english.
Nipples will probably work better when purchasing though.
