no marking i can see except the e and the x
1893? Thanks is there anyway to tell anything about the serial number? All of the metal seems nice andsturdy, ive put 60 rounds thuu it allready it seems fine. I did sandbag it and shot the first box inspecting each shell for expansion and odd mark...nothing so im getting to trust it. Im still amazed that a gun that old is still functioning so well. Any advise on customization to increase the value? Is it worth anything.
