My first post here. I'm proud to own a piece of Schrade history. This particular knife was given to me as a gift in 1986. To my surprise I recently found that it is one of the rarer models (Uncle Henry LB8). I wanted to know what the serial number means on the brass bolster. The number is A7528. Any information would be helpful. Maybe it is just a production number? Can you tell what year it was manufactured by this number?
