Gorgeous work, Tim! You're the godfather of Slave 1 builders!
Actually one question springs to mind, what did you use for the ribbed section on the Dish. In black on the pic above, is it a solid part or single strips?
Tim, were you building a fleet? Were they early attempts, a la Ripley clones in Alien3?
They could indeed be Airfix OMS pods. But I know that on Empire the builders used shuttle SRBs from the G-Mark/Entex 1/144 shuttle kit (currently available from Minicraft) on the Medical Frigate (I positively IDed them for one modeler), so that kit might be another possible source for parts used on Slave 1. Still, this is looking VERY good.
That's because the Entex kit and the Airfix kit are exactly the same. Entex was a distributor of other manufactures' kits packaged with the Entex logo. They used Airfix, BAndai, Gakken, Eidai,.... among others.
