I have attached?4 photos: Micro Trains for the NSE, road #227, it looks like they use the Atlas/Roco tank and their flat car, all most the same blue as Atlas. Roco/E-R road #200 dark blue almost looks like black on the flat car. Atlas road #204, box car red/mineral brown. And Atlas road #208 blue flat car, a lighter blue than the Roco E-R blue. At the swap meets I have seen this car with a slight varying of the blue.?
