Is there a graphic or a listing somewhere of the tang stamps and dates of use? I just received the Camillus 696 I bought on ebay. It has the tang stamp with "Camillus" underlined. It also has the full serrated blade, which I had not seen before on a 696. It came with box and papers. The box looks old school in comparison wiht other NIB Camillus riggers I own. The papers have no copyright or other date. Now I'm trying to figure out something about the age.
