It is a neat tank: very clean look to it. And it's got rivets, lots of them. If I can't dry brush those, I gotta consider model railroads. Very important vehicle too when you get down to it: certainly a move up from the PZII and came in mighty handy. I don't see any desert markings - hard to believe Rommel didn't get any. Maybe that's the point - if it was still considered useful at June 1941 it would have gone to Russia. But I'll look it over real close: right now my thinking is not to blow time on the interior if it isn't visible. (I'm still not sure about the engine.) In the real world we all model for ourselves and practically speaking I could, say, paint only the port side of an airplane. The person that would know is me. And I suppose the hard core would add any detail whether visual or not. I suffer from project fatigue at some point and don't have that in me. I'd guess this kit has an interior because Dragon did a Marder and Dragon has found it cheaper to simply add unnecessary sprues than cut them down. I do have the Tamiya Marder III which I've heard is a very good kit - obviously we do an interior there.
