Does anyone know what kind of rifle this is?

Schuetzen Rifle, is there a threaded hole just in front of the double set trigger?

Hub,
Yes there is and it has a small screw in it...you can see the screw in the last pic.

The hole would be 12" or less in front of the trigger and and may be suited for a bracket.

This also interesting Muzzle Loader Snipper Rifle.

> The interesting thing about the barrel is there are 8 sides on the outside and seven sides in the barrel.

I'm a firearms novice, but I'd venture to say that what appears to be 7 "sides" inside the barrel are actually 7 rifling grooves.

From the shape of the lock and the barrel it looks like a Pennsylvania long rifle.

Here is one with your stock and caliber.

I'll be there behind the griddle, so come hungry.

i would take it off your hands if you have no interest in it. i don't know what it is worth though, we need to look that up

Sorry, I don't have a clue about this type of firearm. But I'll bet the National Rifle Association's National Firearms Museum could help you out.

Thanks for all the reply's. After reviewing all the sites posted it appears this is a Kentucky/Pennsylvania long rifle. Although broken it still make a nice conversation piece...but that's about all.

My brother in-law picked up these two pistols. Pretty interesting pieces.

Thanks again.

Jim

Early rifling was accomplished by flat sides joining each other as described. It was much easier to do that than to cut in grooves as is done with modern rifling.
