Emhar is the only manufacturer making an plastic model of the Whippet in 1/72 scale (and 1/35) for as far as I am aware. The model is made out of less then 20 parts. The model is very easy to build although a little care has to be taken to make sure the cabin is constructed properly.
Decals are provided for English, German, Japanese and Russian examples.

Recommended for everyone wanting to build a very strange looking vehicle. To me it wasn't clear at all what the front and rear part was for example (the part with the cabin was the rear it turns out). Recommended for absolute beginners also.
