I inherited this gun a few years back and was curious if anyone else has or has seen one. Made by American Arms Co. Boston,Mass

I can't see the markings and you don't indicate the caliber, but according to Flayderman (8A-007 through 8A-010) there were only about 5000 of those made. The rarest is .22 RF in both barrels, with an estimated 50 made. Others were a combination of .22RF and .32RF, and both barrels in .32RF, and and both barrels in .41 RF. There may have been some in .38 RF.

He gives a value of $2750 (in my edition) for one in fine condition with both barrels in .22. I think yours would probably go to that level or close. The .22/.32 combo runs around $850, the .32/.32 $950, the .41/.41 around $1750.

A very nice and very collectible item, often not recognized and consequently downrated.

The caliber is unknown I havent tried loading it at all.
Engraved with Wheelers UAT Oct 31,1865-June 19 1866 on one side and
American Arms Co, Boston Mass on the other.

Thank You Jim! I appreciate the info.

I think "UAT" is "PAT" for Wheeler's Patent.

I read that somewhere just can find the caliber size. It's an interesting piece for sure.

You can estimate the caliber fairly closely using simply a ruler and measuring the hole in the muzzle.

A .22 is going to be under 1/4 of an inch, a .32 will be close to 5/16ths of an inch, the .38 will be almost exactly 3/8ths of an inch, and the .41 will be about 13/32nds of an inch.

I see these sell fairly often. Joe Salter had a .32 rimfire listed not long ago, I recall it was about $800.

Heres' one (http://www.liveauctioneers.com/item/6956769) listed for $300-500.

You well see the American Arms Co. derringers listed on the antique gun auction sites regularly. I don't recall ever seeing one bring over 1K.

Thanks for the info. I'm not looking to sell it I'm looking to shoot it and put it back in the safe. Didn't get a chance to measure the barrels.

If it is .32 or .41, finding rimfire ammo will be difficult and if .22, it should not be fired with modern ammunition, though some will say the BB Caps made by Aguila or CCI will be OK.

I would suggest not firing it at all.

Thanks Jim. I guess back in the safe she goes :(
