What Kind Of Gun Is This?

[Funforfree33]

I got this gun from a friend. He had a bunch of old guns in is garage and he gifted me them. I was able to ID the rest of them but cant figure out what this is. Caliber size is unknown. It says On top. J Stevens something Mass. 1864 Any help would be great. Also if anyone knows an around value. I took it to a store today for help but he didnt know what it was but he made me an offer for it. But I dont want to sell it. The numbers are stamped on the barrel, Under the handle, And on the metal stock and all 3 sets match.

It appears you have a Stevens Pocket Rifle (or Pocket Shotgun) made in at least 13 models between 1869 and 1917. The barrel legend could say one of the following or a variation:
J. Stevens & Co. Chicopee/Falls, Mass. (with or without a patent date)
J. Stevens A&T Co. (with or without the patent date)
These rifles were chambered in .22 short, .22 LR, .22 WRF, .25 .30, or .32 rimfire, .25 Stevens-Pope or .32 center fire.
There were also smoothbore versions chambered for .38-40, .44-40 shot, .38 or .44 Stevens everlasting, or .410 gauge.
Some of these with short barrels are NFA guns (as a stocked pistol, they're grouped with suppressors/"silencers", short barrelled rifles and shotguns, destructive devices and machine guns), especially those chambered in.410 gauge. Most, however, qualify as antiques or curios and relics, including those chambered for obsolete ammunition.
More than that I can not tell you without further information (dimensions, detail photos of barrel markings and caliber or gauge of the gun).

I believe all those pocket rifles have been removed by BATFE from purview of the National Firearms Act and reclassified as either C&R or antiques (if made before 1899).

However, if it is a shotgun in .410 (for which ammunition is avaliable) and the barrel is under 18", it is still subject to the NFA and if not registered is illegal to possess.
