This project has been on hold for quite a while as a lot of what i can put on or constuct is dependant on their relative positioning to parts from the Airfix Saturn 1B kit - which i haven't got and is VERY scarce.
But, a bit of progress today thanks to the top blokeness of Keith Scaife, who's very kindly cast me these two discs from the kit to apply to the rear of main section.
No idea what they'd be on a "real" version. Escape Pod hatches? Mine launchers?
