This is an old Ork War Track, it is not painted very well. I included it too show how everything was smaller in the Rogue Trader days particularly the vehicles. Now all the vehicles are not only bigger but plastic. They come with various options you can swap out the weapon, in the olden days you had to get lucky to get the weapon you wanted, even mail order I don't think would guarantee you the options you wanted, at least not originally. Now Internet experts insist there is only one true way to play an army, anyone who does otherwise is an idiot.
