From what I've been able to gather, my LB8 is a early '80's version, s.n. 71699...the knife is fine, as nice as they come, but the sheath that came in the white box with it, has "Old-Timer" stamped on the flap, instead of the usually seen "Schrade"...also, the part that slips onto your belt, is not sewn on, but rather bolted ( I guess would be the way to say it, with 3 of those 6-leaf metal pieces)...shows no sign of coming apart or loose, after 30-plus years... Hope this info helps...
