Change of plan.  I kept thinking of the work involved in taking the wings etc on and off to paint when it occurred to me that if I prime and paint the insides today then I will have to mask them up when I do the priming and this will be a pain.  So  have decided to do the priming in one go, ie inside and outside and then do all the painting to colour on the inside at the very end.

Next job then is to fit all the wings and doors (wish I hadn't taken the hinges off now) and get on with the filling.
