Inherited Rifle - need help identifying

[Fishman82]

I sure could use some help identifying what this rifle is. The barrel is 41 inches long and I measure the bore at 9/16 inch (.55 with a caliper). It has dual triggers. It has "J Kunz" engraved on the hammer side plate, S B N engraved at the top of the base of the barrel, and another name engraved on the top of the barrel further down the barrel. Any help would be greatly appreciated. I am looking to just maintain the gun and use it as a wall hanger.

parts. The Kunz lock is probably worth 4K or so. The rest of the gun doesn't have much value.
