Hi, the following links (if they work) show two you tube videos, in one (Seventies Navy) are clear shots of a Royal Marine gun crew wearing No 8 AWD and green berets and donning anti flash and steel helmets, In the other )Frigate 1973) it shows a clear shot of a Royal Marine in No 8 AWD with red corporals stripes, Hope its of interest?
Regards
Tony
