I did read post 13, thank-you, Jim.
The "1940" looked out of alignment when the image was enlarged and so I assumed that it was.
Is there a reason that everyone appears to assume that this number (1940) implies a date? Could it not just be intended for identification purposes?
I wasn't aware that dates were normally placed on F/S fighting knives, of any of the 3 patterns. I could go and check the 2 dozen or so in my collection but I have better things to do and I am reasonably confident that dates were not placed on F/S knives of any of the 3 patterns.
So why would a "faker" make a good job of producing a F/S knife and then spoil it by sticking a date on it, that is incorrect for that pattern of knife, when F/S knives don't normally have a date stamped on them?
I would say that the "1940" was applied at some time after manufacture of the knife by someone other than the knife manufacturer.
