Thanks Wayne.
A bit late with the promised pics - got side-tracked working on the last GB scores.
Anyway, here's the state of things so far, with the bomb doors painted, dirtied and fitted, along with the main and tail wheel doors, and the 'new' rudder actuating horn in place.
PIC 1. The scratch-built rudder horn which, more by accident than design, ended up exactly the same size and shape as the kit part. It has yet to be re-touched in this pic.
PICS 2 to 4. Bomb bay doors painted, dirtied and fitted.
PICS 5 to 7. Main gear doors painted, decals on, dirtied and fitted.
PIC 8. Tail wheel door in place.
I've discovered that there is a new 'Eduard' PE set for this kit, which has the bomb bay 'windgitter' spoilers included, but at just over half the cost of the ICM kit itself, and with only these two items of immediate use to me, I'll refrain from purchasing it just yet. I may, however, get it at a future date, for another He-111 build, and retro-fit the spoilers to this model.
Next step is to sort out the final fiddly bits, including fitting guns to the nose and gondola transparencies and fitting these in place, fitting the dorsal gun mount and gun, dorsal canopy and cockpit roof hatch, D/F antenna, main antenna mast and wires, and make and fit a trailing aerial fairlead tube, plus a couple of other small bits and some detail painting.
With luck, I hope to get this finished over the weekend, and then move on to the Tamiya Spitfire, involved in the initial interception of the kG 26 raid in which this Heinkel took part.
