Thanks for the info Tinplate. It's similar to that which I worked off, together with a photograph of JZ594, displaying the EIF roundels in December 1944. (I have called the latter SEAC roundels for simplicity. These were 'made', in most cases, by simply overpainting the red centres of the roundels in white, and likewise the red 'stripe' of the fin flash, where aircraft were modified in the field. Of course, the 'correct' dimensions, for reduced diameter roundels, were used at Shore Depots, or MU's in the case of the RAF. The latter were supposed to employ the pale blue centres to the roundels and to replace the white portion of the fin flash, although this was often done in white instread.) The camouflage colours I have mixed myself, working from specs from General Motors Eastern Aircraft Divison, and a colour photograph, and allowing for fading / weathering. As Naval aircraft, and indeed anything east of Europe, are somewhat unfamilar to me, even after almost 50 years of modelling, I found this build rather 'different'! From comparison with contemporary photographs, colour and black and white, I think the overall finish of the model is close enough!
Incidentally, the model is portraying the aircraft at the time of the attack on Japanese oil installations, on 20th December 1944.
Keith, the 'bomb bay' of the Havoc kit is, I presume, the same as in the Boston kit. It's a bit basic isn't it?! I had considered scratch-building the bomb bay, but as the finished Boston (for the Bombers GB) will be in a diorama portraying a particular moment in time, the bomb bay doors will be modelled closed. Also, there's a very good chance I'll need to add weight to the front of the 'bay, in order to keep the nose on the deck!
EDIT: Ooops, sorry Karl! I don't need the figures until the Bombers GB mate, so there's no rush, thanks.
