I have a 10 gauge, smooth metal with almost no identifying marks. Under the forearm is stamped a serial number 28600 and on the plate near the trigger is a code 800 or 008. It is a 30" barrel, and from what I read appears to be a lc smith model from either 1895 or 1920. Appears to be a dark steel metal, with a hammer. Is there a foolproof way I can determine its origin? i need to sell this due to financial duress/surgeries and have owned the bun since birth. My grandfather bought the gun in 1947 for $15. I have seen similar guns for sale from 1200 to 7500........im lost. There is no embossing, nothing on the gun at all other than the two numbers I stated and the serial number is embedded in the curve of the wood itself and not the gun. is that unusual?
