I bought this chunk gun at auction last week. Its a very heavy 1'' octagon , .36 cal. 46'' long barrel . Stock is of curly maple. The gun looks old, and lots of rough around the drum and nipple and un marked lock area . I have not pulled the barrel off as the rusted barrel pins might do more damage coming out. But barrel is solid in its wood cradle. Bore was surface rusty and red, but very shoot able. The only identification , is on the side where it is stamped " I & D LITTLE .Thank You...
