Or maybe a Tiger 1.5 ! Strangely I don't think it looks too bad.

The turret ring diameter of Tiger 1 is smaller than that of Tiger 2.
Tiger 1: ~1850mm (http://www.achtungpanzer.com/panzerkamp ... z-181.html)
Tiger 2: ~1940mm (http://tiger1.info/EN/TigerBSecondSeatingRing.html)

I don't think in real world, the Tiger 2 turret can be matched with Tiger 1 chassis.
Maybe it's OK in model world.

It looks a little "Wacky Races", and I hope the driver ducks when the gunner spots a target
