Yep, the Munster "Wotan" is a faithful copy of the Brisbane "Mephisto", only the gun is different. 506 "Mephisto" is a first lot vehicle while 563 "Wotan" was a late second lot tank. There are quite a number of differences between the two lots, e.g. less rivets with wider spacing in 2nd lot, changed type of louvres, different configuration of rivets at the machine gun apertures, only two hinges at the service flaps with second lot, while early first lot had three, etc. Yep again, the above tank can be identified as 507 "Cyklop" of Abteilung 3. The A7V wasn't lumbering, is was rather fast, in fact as fast as the fastest tank in the Entente repertoire, the Whippet. Both could make 14 km/h. On good ground the A7V was quite a respectable tank, its weakness was the inability to overcome badly churned up ground and trenches wider than 2,5 m.
