Ahh yes! I was going to get one of those but I prefer the almost gothic look of the mark 1! Infact this is the mark 1 tadpole which never got used, notice the longer track fins towards the rear for bridging large gaps
Cool! I also remember that in WW1 conditions, they used 4x4 boards under the tracks so the tanks would have better grip! The only problem with that though is that they couldn't turn then.
