I have a 12 ga double octagon barrel shotgun. It is a hammer side by side with 27 3/8 inche barrels. It has matching engraving on each side of a hound and a rabbit. It has Alexander Gun Co stamped on one side. It has matching markings stamped on the underside of the barrels under the forearm. The markings are 18.4, four designs, a diamond with 12 and another symbol in it, a crown with an oval attached. In the oval are the letters ELG and a 5 pointed star. I was told it was made in Belgium cira 1890 and may have been imported by the EK Tryon of Philadelphia. Hence the Alexander Gun Co. I was curious if this is right and would like to find out the original maker and an approx value. All I know is this gun came from my great grandfather.
