I recently inherited a knife collection that includes the BSA #1002. Has Boy Scout Oath on the back. It has the original paperwork in the box and I believe the number 6-81 may be the date of the pamphlet that tells about the knife, and others. This is No.1996 Scout Knife; No.1885 with blade, punch, and screwdriver is Cub Scout Knife, etc. So my guess is early 80's.
