Last week I picked up this musket. modern target sites aside, it's a pretty decent piece. It's based on the 1863 Springfield musket. .58 Cal and smoothbore. The thing is, the shope I bought it from sold it as non-firing. I have since cleaned it, confirmed the nipple is usable. I don't know why it was deemed as unshootable. It seems to me to be a Indian repro and those are made to be fired, just not completed as such. The only identifiable markings are these stamps on the wrist. I cannot read them or make them out.
