Aeroleather B-3 Jacket from WWII ?

[tempesh]

Hello,
from my girlfriends family comes this Aeroleather B-3 jacket, which her grandfather a german airforce pilot probably traded with an USAF pilot. Unluckily size 38 which is way to small for me. Can someone comment if the Prym zipper is original and with the manufacturers label is it possible to tell me the exact age of the jacket?
Thanks a lot, more images on my website:

Very cool if you knew more details about the trade, that alone would make a good story. Zipper is replaced, maybe a buckle too.
edit it looks like maybe just the zipper pull was replaced. would be nice to get the right pull and put it back on...

Phantomfixer, thanks for your knowledge and sharing it. I will try to digg deeper in that story and might as well find some photos in the family albums.

Your original Aero B-3 dates to early 1942. The waist belts appear to be from flying trousers braces. Originally this jacket would have had a Talon zipper fitted.
