contact these guys, since they produce shades since the 1800's and produced for the .gov during every war.

Sent some pics to AO eyewear, I really appreciate the tip, hopefully they can tell me.

Wow, thanks Wulf, what a find I appreciate that I was also thinking about taking them to the Wings over the Rockies Air Museum to see if they knew anything about them.

The only marking I can find is on the right ear stem hinge, it has two vertical lines a square standing on one corner (kind of like a diamond but definitely square shaped) then followed by two more vertical lines

Try some of the military surplus forums also-I just tracked down a German rifle scope and was surprised at what it was worth.
