Years ago i bought an issue of "le Miroir" showing a very strange american tank...
I was very happy to find a ref on Tank encyclopedia and a booklet about this vehicle presented on landship I immediately bought:

Enough ti stat a scratch base on the 1/35 Holt tractor from Roden.
It is not easy to know what was the real colour and I chosse some "american green to paint the tank :
I hope you like it!
Brilliant scratch build.
If you want more detail how the G9 model was put together - Yandex found a build thread on a French forum:
