RAF Roundels 1939 - 1945
RAF roundel size and colour have changed many times since 1918. The 1939 to 1945 period was especially confusing with aircraft sporting standard patterns known as Type A, Type A1, Type B and Type C. The roundels shown below are those of the above types that I discovered so far, with dimensions supplied where known. Estimated figures are extrapolated from photographs.
Any confirmation of the data - or any amendments would be appreciated.

Note: The roundel types were not painted on aircraft as a set. After Type A there was a mixture of types painted on individual aircraft surfaces and some common patterns are illustrated by the aircraft examples at the bottom of the page. By May 1942, with the introduction of the Type C pattern, matters became more standardised - but aircraft retained Type B upper wing markings until April 1945.
Fin flashes are shown as viewed from the port side.

By Aircraft Surface
The examples are intended to show the diversity of markings - especially in the period up to 1942. It is not uncommon to find formation photographs showing quite different markings on individual aircraft.
