Hi. I have an L.C. Smith side by side Damascus barrel shotgun with no markings or engraving other than L.C. Smith on the side and receiver. When you open the action it has the SN 92525 on the top and R.V. Maurer. on the other. I find it was manufactured in 1926, but have no other ID on it at all. On the receiver when you open it, it has the patent on top and the SN on the bottom with an O stamped below that. Can someone help identify and get a value for this?
