Found this old gun at a flea market yesterday. It's rough, but has some odd features that caught my eye. I'm sure it'll be worthless, but thought I'd ask some experts. I don't see any makers marks on the outside. It's smooth bore, bore measures 5/8" with a tape measure. Under the forstock, you can see what looks like a sight groove for a rear sight further up the barrell if you turned the barrell over? I'm sure it's a repro of some kind, but would be neat if it was a southern civil war gun.
