That's looking very nice Daniel! But why do I have the feeling that you'll be looking around for a missing instruction sheet shortly - then finding it - covered in paint!!
Just a though, but as the Halifax kit is well over forty years old, and they didn't do things like open bomb bay doors on kits in those days, as a rule, are you going to scratch-build the actual bay? I seem to recall the fuselage is just empty aft of the Flight Engineer's station. BTW, you probably know, but the bomb doors are in four sections, split two either side, and fold in on themselves.
