Well fellows back in the late 50s this model was the first knife I owned. I had it until 1975 when it was stolen from my car in Davenport, Ia. Since then I have been looking for another like and finally found it on Ebay. Here it is and I am interested if anyone can peg when this was made. Thanks in advance. The tang stamp has three lines and Reads CAMILLUS on the top line NEW YORK in the second line and USA on the third line.
