Hello Trumper
Without wishing to be pedantic, please note that 432 (Leaside) Squadron is an Article XV RCAF squadron and not an RAF Squadron.
Formed on 1 May 1943 at Skipton on Swale, as the 12th R.C.A.F bomber squadron, and part of No. 6 (R.C.A.F.) Group. I would tend to agree with Eddie that it would be in standard Bomber Command dull red letters, and camouflage scheme for the time.
I have only two small photos, neither in colour, and neither of a Wellington – sorry!
Cheers
Allan
