As a reply to question from Glenn on reversal to Olive,again by Mike Starmer.
A.C.I. 533, 12 APRIL 1944. ‘CAMOUFLAGE. WAR EQUIPMENT, etc.
CHANGE IN BASIC COLOUR.
A new colour, S.C.C.15 Olive Drab was to be adopted as the new basic camouflage colour for all army equipments, in lieu of Standard Camouflage Colour No. 2 (brown), and certain new equipments painted Olive Drab were to be shortly received by units. This new colour had been specially formulated for use in forthcoming operations in Europe. It was intended to be similar in shade and tone to U.S.Army Olive Drab No.9 to avoid the need to repaint lend-lease equipments until such times as this was necessary. This means that any American built motorcycles in British and Commonwealth use initially remained the U.S. colour. The order also stipulated that vehicles will not be repainted simply to comply with the new colour regulation and will continue to be used in the early colours until repainting is due or necessary. This being the case then lots of motorcycles, ‘B’ class and other non-tactical vehicles went to France in their earlier brown colours with dark brown or black disrupter as required.
