Thank you

Des, looking at the pic now, it would have been better I think to have some more variety in wood tones. There is a variation with the little shelf that sits under the instrument/switch panel but this was after the original part was lost and I used a bit of plasticard as a replacement, painted later and separately.
Bo, you are correct. Looking at the model there is clearly no issue with zipping it up now. I have the engine bay formers and bearers painted and ready to put together, so that will be a quick job to include these parts.
I may cut out one of the guns to check the fit in the ammo chutes and supports etc before zipping up, to see if I need to remove paint from the joins rather than later on.
As advised above, I may add some short lengths of brass tube into the drainage holes underneath, and also check the wing root fitting so that I can do any internal filing necessary before glueing the halves together.
