1969 RAF belted greatcoat size 36 long

For sale here we have a really unusual RAF Greatcoat from 1969. In 20 years of trading we've never seen a belted mens example. Perhaps the Carnaby street fashion software the time had seeped in to military rags ?! Who knows. The coat is made from a classic heavy RAF blue wool and has the heavy twill lining.
