The paint is Polly Scale NATO Tri Colors, Black, Brown, and Green. These were all airbrushed through a Badger Dual Action Series 150. Your right about the 50, so I removed it and relocated the feed can and remounted it in the other mount and secured the barrel in the provided barrel mount. The tracks are just dusty from running it. I have on order a set of metal tracks with the rubber pads installed on them. I will have more pictures of the tank as I detail it more.
