Well, its back to vehicles, here is the Airfix Albion fueller being converted to a MkI Coles Crane carrying vehicle. Supplied to the RAF in 1936.
I built one of these in 1/76 scale some time ago, and I not the photos have been deleted.
Again I used the plans I had and scaled them up.
Crane details were very sketchy and so best guesses and total fiction applied.
