Bladerunner,
I'm with Sac Troop. This is a reintro knife, not an original WWII knife. However, I do not believe it is the 1976 Commemorative Club knife. That knife was polished, blued and engraved in gold. Would someone actually use that knife? Could be, but there would be evidence of the polishing, blueing and engraving. I think it is from 1978 to around 1988. 1978 is when the first plain jane knives came out for sale.
Hope this helps.
Best Regards,
Paul Tsujimoto
