Terry, I found some MkIII rails in the leftovers from my Revell Mosquito and, though they are a bit rough, I think I can make them do. Thanks for the kind offer though.
So now it's a matter of working through my lengthy list of small mods and additions. The first shot below shows the three signal lamps that I drilled into the fuselage underside, one being slightly offset, followed by scribing a circle around the holes. Also seen is the scratch built beam approach antenna which was simply made by cutting off a section of an old 1/72 scale tail wheel, drilling a holes, and inserting a length of stretched sprue.
I've not yet decided which of a couple of options I will use to finish off the lamp lenses but, in any case, this will be left until after the underside has been painted.
Behind the nacelles, the fuel dump outlets were drilled out (I might have shown this already as I did this some time ago).
There's a small blister on the port side of the fuselage under the turret that I made by making a slanted cut across an end piece of sprue and shaping it into a tear drop. The more I look at it, the more I'm inclined to replace it as I think it's turned out a bit on the large side.
On the opposite side, I decided to add a patch for the flare opening. Period photos show both open and patched holes but I have no photo of this for my particular aircraft. Once cured, I will file the patch down as it's a bit on the thick side.
That's it for now. Thanks for looking in.
