I don’t think that one is coming back.
:D
I got a big kick out of that one episode of ‘Lost Gold Of WWII’ when the crew uncovered a knife in the tunnel.
They immediately ran it back for analysis thinking it was from the 1930s.
I immediately recognized that knife as a US govt issued knife - one of which I still possess when I worked with the USDA.
After losing a couple of them over the span of my 30yr career, I finally held on to one that I have since I retired in 2009.
