...I have measured the superestructure of the kit. The real vehicle measures 3.4 meters wide, and the scale model measures 97mm.
This is almost exactly 1/35.
It seems that the total length (barrel included) is slightly inferior to the scale model of Tamiya (278mm Tamiya vs. 270 Trumpeter).
I'm very confused.
Why you say that the scale is 1/42?
