I have a rifle that appears old but minty. It is a single shot that breaks in two for transport. Metal butt plate. The serial # is on the barrel and the wood of the butt stock on the underside near the receiver. It came with and resides in heavy canvas case w/ leather straps that when all put away is only about 18" long. I suspect it was for a saddle. Just trying to name it so I can learn a bit more about it
