A 3 star tank (ensuit in every sponson, cable magic lantern etc.) Well actually this is an attempt to give an impression of what the Mk V*** would have looked like based on the wooden mock up. Note the commander's turret seems to have been deleted from the design but the driver's cab it larger so perhaps he had a seat in there. I'm sure that there would also have been lots of pistol ports etc but where?Your guess is as good as mine if not better.
