Spitfire PV202/161 returns to Duxford

James,
You are welcome, but I thought that the next question would have been “what is your source”. The answer would be “I have read the file”.
Regarding the Celtic Boss, the original idea was to include all three of the national colours, but with war approaching it was decided to reduce the visibility by dropping the white segment. Later a white square background was included with the fuselage boss at the request of the army units to avoid confusion with RAF aircraft operating over and around Ireland at that time. This lasted up to and including the purchase of the Seafires in 1947. New aircraft purchases reverted to the two colour boss and lasted until mid 1956 as listed in the previous posting.HTH.

Thanks Tony.
That’s the ‘when’. The other question would be ‘why?’ Is there a difference in the origins or history of the two versions? Are they different things or different versions of the same item? It’s presumably not the same as the removal of the red from the SEAC roundel, a potential confusion item…

Cheers, TIA

The 3 colour boss came into use following a directive in mid 1956. The first to use it was the Chipmunk aircraft followed by 3 Vampire T55 delivered in the new scheme in July 1956 and the other aircraft followed as they went for normal serviceing or majors at the MU.

Dumb question time…

When did the IAC ‘Celtic Boss’ marking change from two colour segments to three?

Thanks for posting YR
