[Coors 54]

Thanks to all for your input. Confounding the Reich answers most of my questions, the aircraft could carry bombs and incendiaries in the bomb bay or the extra long range tanks depending on the mission profile. Late war sorties seem to have carried bombs as a matter of course.
From this I would deduce that the instrument panel was laid out as a standard FB VI with the bomb selector panel on the right and the ASH scope etc would be shoe horned next to it. The Sea Mosquito layout idea is a good one but probably had a bit more thought put into it so I'm not going to follow that.
The rear shelf had several other black boxes added to it and pictures show two small intakes next to the ASH radome at 5 and 7 o'clock presumably for cooling. As late production aircraft they also carried the landing lights in the starboard leading edge not under the wing. All escoteric stuff but important to model geeks!
