Salvaged parts guns, build with mismatched, ungainly parts, and architecture, are often called blacksmiths guns, out here on the West Coast. Many guns suffered damage getting here, in the old days. the wood usually was long gone when the owner took the metal work to the local blacksmith, to barter for something he needed. The parts languished under the bench, until the smith found time to assemble a gun. These gun could rarely be confused with an original manufactured rifle by a trained gunsmith, due to their odd stock shapes, and mismatched parts. I've seen literally hundreds of them. Some with rare parts included in the mish mash of their new life as a working gun.
