Japanese Flight Helmets

[Lt. Martin]

I have found two WWII Japanese flight helmets, one of which I may buy.

#1 Army summer flight helmet:
The seller says:
" The helmet is complete but shows wear and use telling us that this particular example didn't sit in a storage depot somewhere but was actually worn by a Japanese Pilot during the war. There are sweatstains around the edge of the helmet and the lining shows wear and use." (which in the pics, there is)

Should I believe this?

#2 Japanese winter flight helmet:
The seller says:
"Nice quality leather helmet with rabbit fur lining. No damage to be seen, just shows light wear and use."

Were the winter flight helmets used only in the winter, or did the pilots wear them because it gets cold when you are flying high?

(cant upload pics right now, my computer will not let me?????)

Many Thanks

I cant find any websites with information about Japanese flight helmets.
