Glenn.
I have actioned as per your request.
I agree that the 55-292 profile is not justified particularly as the photos relate to the later registration.
The practise of reverting model designations to the civil equivalent when military airframes enter the civil register is not something I necessarily agree with. Civilianised Chipmunks are treated this way although they continue to fly 'as is' even to the markings.
Thanks to Ken we can have 55-0292 with its correct model designation!
Malcolm.
