You'd need to enquire on a specific serial number, Phil, as different batches of the aircraft could be built by different contractors - e.g. Camels by Sopwith, Ruston and Proctor, Hoopers, Porthome, Boulton & Paul, Clayton & Shuttleworth, Nieuport & General, Beardmore, etc, etc who might each have their own interpretation of the painting spec. An individual airframe could then be rebuilt at an aircraft depot and could be recovered at a squadron repair facility.
Hence there could be substantial variation even for individual planes with consecutive serial numbers.
It's a bit of a minefield and you need to look for documentation on a specific aeroplane.
