Thanks for the photos and background information, Ben. When you first showed it I thought it looked good, but now I've seen more, it's amazing, unbelievable.
I would never have guessed that the body came from the RC train range; it's not something I'd ever have thought of looking at for ideas. But, as you saw, it offers everything - space, roller shutter doors particularly.
Great work, Chief!
PS: I wrote the above before I saw the photos in your later posts. Now doubly gobsmacked!
