Possibly of interest to this forum is the 080 French tank manufactured by Jouef in 2 different versions, open and closed cab. I have used the works photo of Emanuel Clegg scaled to 4mm using a photocopier from the wheel dimensions and the wheelbase and valve gear looks to be almost spot on. Not very scientific but near enough for me! The cylinders are slightly different and the wheels are not the same appearance. They are also slightly too small but a ready made chassis would make construction easier. Everything above the chassis would have to be scratch built.
I have owned and repaired a number of the Jouef tanks, the original version was made for Playcraft international and had a 3 pole motor, pick up from only two axles and a gear drive. They also have peco type couplings. I have installed extra pick ups on mine and they run very well.
The later version sold under the Jouef brand has continental couplings, five pole motor and a (usually) poor rubber band drive instead of the gears. They also have pick ups on three axles. These tend to run much better when properly set up but when the rubber band slips thy don't move at all. A Hornby class 58 traction tyre is approximately the same size and I have used them to replace the Jouef original.
