i work for a trash company in indy and had a customer tell me he was cleaning out an old house and some how we got on the topic if the person was in the military. anyway he said they found a barrel in the house and started to describe it and i told him to bring it in and i might be able to tell him what it goes to. well he brought it in and its a 1903 barrel marked with the flaming bomb cartouche and date 2-44. he actually said you can have it. its got a little surface rust very light actually on the outside and the bore is nice and shiny. any thoughts what to do with it?
