Help with muzzleloader ID

[Jetmech]

Good afternoon,

Acquired a half stock percussion rifle, .25 caliber 3/4 inch barrel is about 38 inches long. Rifle's overall length is 53 inches. No maker's name or initials on barrel, lock plate is engraved with the initials R P.

Multiple pics attached.

Just wondering if anyone has a opinion on what area of the country it may have originated from.

Thanks,

Jeff

Looks Ohio hog rifle to me I had the stock of one similar but thats a wild guess it had neither lock nor barrel but did have a note under the butt plate pinning it down to Darke county possibley Switzer but that.s pure guess though he was a noted Grenville area maker' I might be being a bit rude with the' Hog' bit but it looks fine to me .
