Been busy over the last few months with the A7V chassis and variants, and this is the ultimate monster.
I believe it was only ever a prototype (3 built...?), an extension of the Uberlandwagen transport vehicle with a ridiculously long load area and two Russian 76mm M1902 guns for use as AA weapons. As before, I can build this to order if anyone is interested, the Uberlandwagen is also available but I need to take some better photographs of that first!
I've shown the version with a frame over the cab which I think has light folding armour for when the AA weapons are in use, I've modelled the armour "up" as well but not shown in these pics.
This is in 28mm by the way.
