I tried searching the classified ads but did not have much luck.
It is a .50 caliber Huntsman barrel. In really good shape, just a couple of years old and rarely fired.. Blue is a little spotty at the muzzle like a sweaty hand print. Scope base installed. Ram rod and forend with sling swivel. Original breech plug with a bunch of carriers and the 209 conversion never to be mentioned plug. I have wrenches for both plugs.
Just a ball park figure would be good.
Thanks
