This Corps was only formed under Army Order 70 of 1942. This, with the King's Crown, would have been their first badge. They were specialist mechanics chosen to help out in other units and were formed into Light Aid Detachments when attached to the likes of an Armoured Regiment. "Quartermaster's Comment":- Until 1973 they even served aircraft for the Army Air Corps. Most personnel came from their parent, the Ordnance Corps but some came from the Royal Engineers and the R.A.S.C. They finally got their present title per Army Order 148 of 1949. This badge is nice; it was obviously made in World War Two but looks as if it has never been used. As you can just pick out in the photo, the name of the maker, GAUNT of LONDON can be found stamped on the brass slider.
