These were fuel jettison pipes.
2) Visible through window geodetic stringers. I assume that the glass is on hte outside and the framing need to be painted from the inside? Presumably same color as fuselage nearby?I agonised over this very problem, because to my mind, the framing is very much part and parcel of the Wellington's character. It is the geodetic aluminium structure which is visible through the perspex windows and as you say, to be accurate, it should be painted on the inside, but that way, I found, lies madness!
I've always taken the view that it's the visual effect that counts rather than total accuracy, so what I did was painted some Tamiya masking tape (nice and thin) silver and cut thin strips with a steel rule and X-Acto knife, then applied these on the outside. After a coat of varnish, I felt they looked convincing enough. I actually made the Coastal Command version and it looks suitably different.
