I have a model no 1 that I bought in the middle or late 70s.I got it to take on fishing camping trips to northern Ontario.I used it hunting hiking camping for over 25 yrs before I retired it.I once told a collector dealer at a gun show that I had used it for everything from gutting deer to cleaning fish and I once dug a latrine in a emergency.He auctualy stuttered when he told me it was for showing not using.
