My cousin was given this gun and he gave it to me. I have no clue what it is.
I've oiled it a bit and looked all over for some numbers and or markings and have seen nothing.
Does anybody have any ideas

Looks to be about .32 caliber, percussion half stock rifle. Missing the hammer and ramrod thimbles.
