The helmet looks to be either H-3 or H-4 model. This was from the Stingers fighter pilot squadron VH-113. The Korean helmet is authentic and original looks to have been totally restored with original paint and hand painted decals of the stingers squadron with beehive painted on both sides of the helmet also has the original US Navy wings logo on the front of helmet. Helmet comes with inside liner marked original microphone.
WWII fighter goggles will come with styrofoam head mannequin. Douglas flew many different fighter planes and also flew in the stingers squadron on a aircraft carrier thats why he treasured this helmet. He was on the USS Antietam aircraft carrier.
