"BLC" is the Nazi code for Carl Zeiss. Dienstglas is German for Service Glass. Definitely a wartime Carl Zeiss binocular. Looks to be in good shape too. You might try going on ebay and doing a search for the binocular there. Lots of old wartime stuff is on the sales block. If nothing else you can get some idea of value.
These were definitely "picked up" in Germany.
you have a pic of them?
My grandpa landed on Omaha Beach. He was one of the Tough Hombres. He eventually ended up in Germany. I've got a whole bunch of German "stuff " he picked up. They took a castle type building and used it as a base. A couple of the German prisoners gave him some of their stuff. I have 1 each of Hitler's youth program gold cross and silver cross. I'll not be able to know the history of the bino's as he's gone now.
