Many years ago, I did have an original, vintage Poughkeepsie A-2 flight jacket.

I believe Eastman etc follow the same patterns.
It was cut slim. It was size 42, but this was more like a modern day size 40.
It was cut shortish, perhaps because trousers used to be worn higher on the waist.
It was cut for a trim young man, not a middle age beer gut.
A-2 never had a sheepskin collar. G1 has a sheepskin collar.
A-2 never had hand warmer pockets. Reminds me of school, You there, hands out of pockets!
