We now have a stat screen with fuller stats plus some more pics. Click to enlarge. The description in the screen shot goes roughly like this:- The machine was developed by the Swedish company Landsverk for the Swiss armed forces. The tank was supposed to be armed with a Swiss copy of the British 20 Pounder tank gun. To verify the correctness of the decisions a full-size mock-up was built, but development was stopped in favor of the machine in the thirty-ton range. The vehicle was never built.
