Boy the difference between the Tamiya, and the Italeri Marder 3, they almost look like two different tanks, just about the only thing I noticed the same was that little box on the right side with the holes on top, the way my armor is, mine couldn't have those seats put on it, and that back rack that almost looks like a seat on yours, it is flat with the floor on mine. Your ammo storage, now that is all open on mine to where they can jump down to the drivers compartment, even the guns, to where yours is smooth all the way back, on mine, it has a raised ridge by the barrel transport lock, I could go on, and on, like I said, the only things that look the same is that little box, and the name. I wonder which one is the closest to being correct.
