Hi, I picked up what I was told is an original, first release paramilitary knife. I'm trying to authenticate it. I have been sent a couple photos from a collector who has one, and i can see the stock photos on this forums site on the archived products page. But I can't seem to find one that shows me the compression lock release bar- this one has jimping where you press it to release the lock. And the pivot hardware is unlike any I have seen. Although I have taken pics, I don't know how to post them if the process is not very automatic.
