The same post should answer stephen210's question (it's green). Sorry to those of you waiting for me to photograph my G4-B, I'll do it ASAP.
Thanks for that info :thumbsup
Would you happen to know about Lambert's jacket aswell? I've been looking but not come across anything close.
Lambert's vest appears to be made from the upper part of a G-4B flight suit.
Sorry for any confusion, i meant this jacket...
here's the real colour of the crew jacket. As you can see its not brown but whats called "purple Taupe" or a variant on that family of colours, hopes this help people who are dye-ing.
