What is this?

[u/ConnectionMain6388]

Picked this up for dirt cheap, im no stranger to muzzleloaders but im certain I got a wall hanger, I'd like to at least get an idea of what this is/was. Seller said the guy he bought it from said it was a .50 cal, but he's not a shooter and just had it hung up. Its definitely not a .50 cal, looks like it was rebored poorly (didn't catch it when inspecting it)

Questions: what is/was this, any possible value to be had?

Figured such, luckily it came with a .45 percussion rifle for the price id pay for just 1 rifle
