Goggles, Polaroid, M-1944, N-2, US Navy, in Box

Genuine WWII US M-1944 Polaroid protective goggles, black molded-rubber, bearing mention USN and dated 1945.

In quite good overall condition, the present goggles come with some spare lenses in their paper envelope -- white (standard), green (to be used in sunny weather) and red (designed for dark adaptation).

Nice homogeneous set, in its original cardboard box marked N-2.
