I was finally able to get the 3rd road number of the Atlas O Grand Trunk Western 3-bay cylindrical hoppers to make a complete set of 4 GTW hoppers. High-end O scale Grand Trunk Western freight cars are hard to find, so I now order all of the numbers at one time, if possible. These GTW cylindrical hoppers used to be a common sight on GTW trains in Michigan between 1990 to 2000.
