I have a scaled down, walnut stocked, smooth rifle that has a barrel which is 38 inches in length. It has an intgalio marked lock by M. Sheets, and has been converted to percussion from flintlock. It has a cheek rest and a nice VA side plate, but there is no patchbox. The barrel is octagonal to round with two transitions, and a greatly flared muzzle. It is, in my opinion a Spanish barrel that appears to be much older than the rest of the gun.
