Hello everyone, purchased a real nice schrade 507sc with cougar print. I payed $43.80 for it. It has paperwork and sheath but no box . How did I do ? The knife is unused and pleasing to the eye not to mention a well built knife. My question is when was it produced the paperwork has the date 1991 on it. Does this reflect when it was made? If not how can I date it? It has 4 pins unlike my other LB7s that have 3. Any info appreciated. Look forward to reply. Thanks 253barlow, Mike. P.S. hope this is right spot in forum for question
