Original British Brown Bess Barrel, 39 1/2" Long. Has British proofs on breach and has original bayonet stud towards muzzle. Undrilled touchhole and approx. .75 caliber.
A very nice original barrel but not guaranteed to fit your gun as all guns were hand made.
I believe the touchhole was welded years ago and has not been drilled again. This allows you to fit it to your lock.
