Aloha All,
The yellow IFF leading edge order is dated 11 Sept 1942, the initial rubber stamp (sent date?) is 12 Sep 1942, the second rubber stamp (filed date?) is 13 Sep 1942.
For the IJN, Kasumigahara Kokutai tested the red stripe and the yellow stripe versions prior to the issue of the order.
Cheers,
