The 2 guys on the left are wearing the Artic Field Jacket, a winter jacket based on the M-38 / M-41 jackets.I'm posting this photo as it's an excellent sampling of jackets worn by the men stationed on a USAAF base in Alaska during WWII. Looks like examples of A-2, D-1 and B-3 jackets and B-2 caps. I think the canvas are 2 B-9's or possibly one is an M41.View attachment 64703
This place is here for that very reason...Thanks for updating me.
Have you ever seen John Huston's documentary REPORT FROM THE ALEUTIANS? Tons of great footage of flight kit.
