Thanks for your answers. Is it produced in the US in 1942 and is it possible to say if it “served” in the US army during ww2 and after ww2 were supplied to Greece or was it supplied to Greece during ww2?

The photo is not of John B. Crandall, but of his brother Richard B. Crandall (Sixth Vermont Infantry) - brothers - both ancestors of mine.  Richard B. Crandall (in the photo) was killed by a sharpshooter in the battle of Cold Harbor.  I'm writing extensively about him.  I have included photos of John B. Crandall.  Should you ever be interested in offloading the medals, I would be interested, although I don't know the costs of these sorts of things.  

Definitely not Vietnamese related at all in my opinion. Construction doesn’t resemble any Asian made patches. Not really sure if this is even a military piece 

Thanks everyone!      

Thank you for your reply, Honestly the value doesn't matter to me so much as any potential history of the piece. Is it known if stuff like this was done during the war, interwar period, WW2? Or are knives like this pretty much exclusively assemblies from far later? Regards, Andrew

Have a great show! 

was able to visit Pvt. Wolf today    

Many thanks for your information which has already enlightened me a lot, another question for the weight of the US 105 boxes how to calculate with the ++ what does a + correspond to?

There weren't a lot of SEALs with SOG/NAD/Op 31/37. I'd need a name to check my records. As far as I know, there was no such thing as Phoenix Program Gold team.

early rangers/scouts in training? the lighter weapons make me think of a unit that would travel light for those kind of missions. Also, Marines and Navy CB's would have been issued 03's at this time right? definetly an interesting photo.
