Un-marked JPK's

[52248bj]

Hello, I have several Camillus Jet Pilot knifes in my collection. I've been looking at one for sale but it has not tang marking or pommel marking. At first look it doesn't appear to be a replica or a knock off. I even counted the teeth on the saw-back and they are correct. Does anyone know if Camillus or Ontario ever made un-marked Jet Pilot Knives.... thank you

There are very noticable differences in the Ontario vs Camillus manufacturing of the Pilot knife.
The only thing I do know is that Ontario made some of the Mark 2 knives without markings (sterile) in the 1980's.
I believe those went down south.
