Warmtoast,
I have my late dad's flying suit, boots, helmet and gauntlets in his old trunk in the loft. It looks identical to that in your photograph. It comprises a heavy canvas outer in olive drab with a dark brown fur collar. The inner is a down filled silk-like material in dark brown and both suit and inner are marked as 'Sidcot Suits'. Indeed, this is what Dad always referred to them as. He joined in 1942, training in Canada and then being sent to Burma on Dakotas. My Mum has just passed away and I have inherited the suits and intend to display them on a tailors dummy in a suitable location yet to be decided! I too have a photograph of him standing on a wooden hut step in Regina during his training in the flying clothing. He also told me that in Burma he usually flew in KD shorts and shirt and not the Sidcot Suit due to heat
