Karl, that is a mighty fine build, the rust on the extra piece of track is real good. The only thing I would do different, if I was you, sense your tank is so clean, is your tracks.
With it being so clean it would show a lot more shiny parts, like where the wheels rub together, plus the tracks themselves, would have a lot more wear parts showing, being clean like it is.
There is a lot of metal touching as it moves, which in turns makes it shinny, now if it was a lot more dirty, then it wouldn't show, it only has to move a little bit to shine up them tracks, anywhere it rubs.
Now them mufflers, I have no idea how well they kept up on replacing them, so they could have gotten real bad I have no idea, you need an expert on that.
This is an academy das reich Tiger.i added no aftermarket items at all ,the tracks are individual and are from the kit,but i used a set of Tamiyas road wheels as the academy ones are crap.i like the way the Tracks ended up,i used a mix of black and brown,then weathed them with mig powders and to finnish of i used a silver pencil for the track wear.hope you all like it ,please leave me some comments,Thanks
