Need help to ID a Muzzleloader

[olderthanthehills]

Hopefully, someone may be able to give me info and value for this muzzleloader that has been in my family for at least 100 years. It belonged to my dad who was born in the late 1800’s.
* It has no identifying marks whatsoever. Maker unknown
* 35” barrel
* Rear section is octagon 11” long
* Front section is round 24” long
* Bore believed to be 54 caliber
* Has 3 lines across the top of the barrel where it changes from octagon to round
* Believed to a Kentucky muzzleloader made in Pennsylvania
Any info would be greatly appreciated!

looks like you've got a smoothbore, a 54 caliber translates to a 28 gauge. Being percussion it's post 1840 manufacture. I'd have it checked by knowledgeable black powder gunsmith before shooting it.
