fyi: i have an mint 1947 star g-1 that has knits [perfect condition] that have faded to a reddish color much like an aero a-2. the muton collar also is faded. interestingly, the goatskin hides are still dark, creaky and as i say, in pristine condition. when i first got the jac, i thought that the knits were replaced, as i have never seen reddish knits on a g-1. close inspection proved that the knits are indeed original. all of this led me to poring over as many wwll pix of g-1s as i could find, to see if other originals had reddish knits, and yup, this does seem to the case in a few jackets. dye lot? specific contract? dunno, but it looks sharp.
