Posting this from Tom:
*** Camillus made the first run of the 5" Pilot Survival knife with the date stamped butt on 11-28-66. I am not surprised to see a knife like you have with both the blade and butt stampings. Nothing ever got thrown away. If the extra blades were not used for a government contract then they would have been used for knives made for the civilian market. Do you know if your knife came from a military or nonmilitary source? Camillus would regularly bid on the military contracts and also supplied knives to other companies that received contracts. We used to sell the MC-1 Paratrooper's knife to companies that had been awarded contracts for survival kits. I recall one time getting a call from a customer wanting to buy the 5" knife for a contract for the Taiwan Military.
*** I have attached the manufacturing information for the first 5" knives made in 1961 and the butt date stamped knives made in 1966. The production figures are for the date stamped knives.
*** Camillus lost the contract for the 5" Pilot Survival knife to Ontario Knife Co. around 1984. I believe that after the date stamped butts were used up, the stampings were then done on the blade.

Tom you ask a good question regarding the origins of my JPSK with the double marks. The owner did get it while in service. But he remembers it as a private purchase thru the PX. Ive talked to more than one veteran who remembers these knives being available thru the base exchange and saying that they were the exact same knives that were also issued thru normal government procurement. Not foreign knock offs. I also know first hand that the JPSK's could be bought as new on the commercial market back in the 70's at least. I wondered if there was something fishy going on at the time. Thanks for clearing that up for me.
I believe the PX system worked independently of standard government procurement and I know they often bought goods for sale from makers like Buck,Camillus, Case, KaBar, and Western. Im sure there were others too.
Nice to see the S-card with the 61 date for the 5 knife.
Also I now have something else to look out for
a pommel marked Camillus pilots knife dated to 1966.
