Shelby I had found several Winn's in the Marion Alabama area but the way it is stamped I didn't think Winn was correct. As I typed it there is a period before the complete stamping and also after it.There is no space between the T and theW but I can find no gunsmith listing for TWINN. It's a very short,heavy barrel full stock,three barrel keys and a beautiful long "National Road patchbox with weeping heart cutouts. No lock,no trigger assy and no trigger guard.Looks like it's been laying in a pile of you know what for the last 150 years. Again Thank you for your help George
