Japanese WWII Navy winter flight helmet

[mjacobs784]

Might you know if the Japanese M-30 Navy winter flight helmets were made after 1941? I have one which label reads Yokosuka Naval Supply with a showa date of December, 1943. (12 month 18th year). Trademark label, says Nagata & Co, Tokyo. I read where they were made from 1939-41. Any info will help confirm this.

In my experience the "cut off date" for many cloth items is not a hard and fast thing. I have had flight helmets in this style that were in 42 and yours is "proof" supporting an even later date. This style was replaced with a simplified version in the mid-war time frame - it was not obsolete - it just had some features that were considered wasteful as the materiel shortages became more obvious and eventually acute.

The winter version of this is actually my favorite version - nice item

If you happen to locate another winter Navy M-30 with an earlier mfg. date, dark leather and the rabbit fur, issued if possible, please let me know. I need one for a display use. Thank you.
