A member at ARC informed me today that I may have made a small error on my conversion so far. Turns out the windows at the rear of the fuselage were not flat panes, but rather cylindrical shaped on the SAR Lancasters. I may try and fix that before its too late in the build to do so. Another feature of the SAR Lancs is a barrel shaped radome located just behind the bomb bay doors. I didnt take any pics tonight, but I managed to make a close facsimile of the ventral radome using a 1/48 Eurofighter external tank and an unused part from the lanc kit as a plug. Once it was all glued together and the glue had set, I chucked it, that is, I mounted it on a nut driver and spun it on a 12 cordless drill while I sanded the shape. Its not perfect, but it looks the part.
Before I started with the primer coat, I discovered that one of the canopy side inserts had somehow gotten detached and had set slightly inside the main canopy greenhouse. For some reason, the Revell Germany clear parts don't seem to work well with the Tamiya extra thin, I had issues attaching all the clear parts. Anyways, I had to break the part loose and attach it from the outside.
I did a better job than I thought with the seams, as only a few were visible underneath the fuselage once the Mr Surfacer primer coat was applied, a little light sanding should fix that. A few panel lines need to be fixed, then I should be able to start painting.
