WW2 AN-6530 US Army Air Corps Pilot Flying Goggles

WW2 AN6530 US Army Air Corps Pilot Flying Goggles. The foam piece is free from one of the eye pieces. There's some rust on the metal frame.

I haven't tried to restore it, though I've found disassembly instructions. A vinegar soak followed by a scrubbing with an old toothbrush should do a lot to clean up the metal frame. I've read there are glues to get the foam back together as well as reproduction foam pieces.
