During 1975/6 the wartime "Hairy Mary" working dress uniforms were replaced for all ranks with the 1971 pattern No 2 uniforms. Made of a smooth woollen and man-made fibre mix material the jacket was a loose blouson design with a front zip fastener and epaulettes, often referred to as a 'Thunderbird jacket'. In the mid 1980s RAF blue crew-necked woollen pullovers were replaced with a new V-neck design featuring blue-grey cloth elbow and shoulder patches plus a pen holder patch on the left sleeve. The Thunderbird Jacket was withdrawn in the 1990s and replaced with an additional pullover, the design reverting to a round neck but retaining the pen holder, the official description being Jersey Man's (Woman's) Blue Grey Round Neck.
