Acquired this at an auction, best I can determine this is 1950s vintage Flak Vest for flight crews. Please correct me if I'm wrong. Any additional information would be helpful. 

Thanks

Derived from flier's armored vests, these were first made late in WW2 for the infantry and saw combat in the Korean War. The armor plates were aluminum. A simple Google search will provide plenty more detailed information.

Thanks for the information. I did a quick search for it, but kept coming up with M2/M3 vest. I'll look again with the information you have given me. 

Thanks again.
