I will make this a general thread for my 2nd edition 40k orks, instead of just the tank.
Just painted this. I will add a tank commander when I have painted him. Painted with Tamiya enamel spray (Dark Yellow TS3) then GW Desert Yellow with increasing amounts of white added for the highlights. The Tank is a 1:48 Tamiya Marder III and in game will be used as a wartrukk with either heavy bolters or autocannons depending on how many points are free.
There will be an army to follow with mainly RT troopers with lots of 2nd edition models as well. This is the first model. I couldn't resist painting the tank before any of the foot troops after getting hooked on reading Da Great Queeg's excellent blog

The second picture is a bit more yellowish than it is in real life.
And some slightly blurry photos of the tank gunner before he was attached.
