Need help to I.D. my Muzzleloader.
I bought this .54 Caliber muzzleloader a few years ago from a local FFL dealer who unfortunately died shortly after of cancer. I have exhausted all of the resourses that are available to me. Pictured is the receiver and the only markings on the rifle, other than the SN#, if anyone recognizes these or the design please let me know. The primer retainer is broken and before i alter it at the gunsmiths i would prefere to replace original parts.
