Russ,
There are a lot of questions to answer to help identify your buddies old knife. Sending it in would be the surest way but short of that, if you could send a photo or JPG.
Make sure you send it to
BKI, NOT Buck Knives Inc., that just tips any dishonest mailcarrier off as to the contents.
Take care,
