Drs. Drew and Bill , I have a 12 gauge Gladiator hammer gun. Barrells are 32 inches long and look to be steel. Chambers are 2.75 in. choked full and full. Barrell flats are marked with the ser # 179xxx over F. On the under side of both barrells is either a 10 or a 01 , a 4 and what looks like a C. No LLH. On the left sidelock it says Gldiator where it usually says LC Smith and on the right side lock it says nothing. Gun is in remarkably good shape considering it was a low end field gun from sears. The but plate has a dog with a bird in it's mouth ( very similar to a parker ). I'm going out and buying a digital camera this week end and will try to send you some picture. Hope this helps.
