Were not RE City and Gieves one and the same? I have a Gieves Greatcoat I bought second hand in Plymouth when RAF Mount Wise closed down. It had had a red silk lining, but it had been roughly removed. I had that reinstated on a foreign tour where the tailors were affordable. I also picked up an RE City No 3 Mess Kit (probably owned by the same chap who sold the greatcoat) - it still fits well but it is heavily quilted, no doubt from the days when Messes did not have central heating. If worn with a waistcoat, it can be uncomfortably warm. But I wont be wearing either items again. I'm holding on to the greatcoat and mess kit for sentimental reasons.
