I bought a Fine Scale Modeller magazine yesterday and it had a Model Expo catalogue in it and then I saw this:

Then........
Whilst checking out the Lindberg site I found this

They are not 1/144 scale and a slightly later era but the shape is there as well as the size of course 38+ inches worth. Both models are huge and could be just simply built as is and used in games or could be very useful starting points for converting to a smaller (fictional) Zepplin in 1/144.
