Unfortunately, the scale can't be used as a guide as the images will show at different sizes depending on screen settings etc., and much the same goes of printing them off. Dimensional data is needed. There are figures in Tankette from David Fletcher and Dick Harley's superb series on early British AFVs years ago. Speaking of which, the French drawings are suspiciously similar (in fact, identical) to Dick Harley's Tankette drawings. I'll look them up and post some figures later.
