This wasn't from one of my episodes. I will look into it. Funny, in 4 years, I never used that ship. I seem to remember seeing a sketch from John Eaves of it. I will look through our ships prints and let you know.
As for the half saucer, I'd have to do a side by side to see if it's the same diameter. However, yes, any and all parts where pilford if possible! Only way to get things done!
