As I said unfortunately I don't have any evidence or proof to prove this. However the tunic is fitted with a nice selection or wartime andniustboost war medal ribbons. A gold bullion set of RAAF pilots wings are fitted to. All buttons and belt in place to. Makes a very nice displayable tunic.Size wise the chest measures 21 inches from armpit to armpit so should fit a 42 inch chest. Shoulder to cuff measures 25 inches. Overall a nice displayable tunic, ideal for a ww2 RAAF musuem display, collection or reinactor use.
