It is an interesting gun. It's a little more modern than my selection of high walls, so I wonder what it was made for. The barrel looks short and heavy and makes me think it may have been a varmint rifle. But the caliber is a bit heavy for a woodchuck gun. It had me wondering initially, if it might have been a takeoff barrel from something else but apparently not.
The lack of a set trigger strikes me as odd, though I know that was common in the era. An interesting choice for the front sight as well.
I'm curious about the internals. Does it cock on closing like an original would? Does the firing pin retract like an original? Does it have the Niedner firing pin?
