I was lucky, in the 1980's there were several vintage clothing shops in Nottingham where I lived. They used to import old clothing and had no idea about military items. I built up a good rapour with the owners and got first choice of the "Army" stuff in the end. I advise them what they had and got the stuff I wanted at a fair price. Once missed buying a B15 flight jacket which had a small escape kit (a hacksaw blade) sewn into the sleeve.

Cheers, Ade.
