Well, it's a nice, old, well-worn rifle very typical of what folks used during the 19th (and, in some areas, well into the 20th centuries) every day. The smaller caliber was also common and if it has been freshed out, it still had a lot of "life" left. The front action lock was always a percussion lock, but the barrel ..who knows, may have been converted. What I see is contemporary with it's age.
Some prefer fancy-dancy, mint, unfired engraved, elaborate patchbox rifles, I like just what you have - an honest old hog rifle we wish could talk. Fun stuff. Thanks for posting.
