You should pick up the ones in the WM speed lettering. Mine is in the old circular logo. This would be a rare car in this paint job in the Chessie Era. The speed lettered ones (also offered by Bowser) are much more common. I plan on getting some of those too. You need some of these small rib sided (Pullman Standard type) covered hoppers to compliment the small ACF covered hoppers. Chessie had both, and they both ran together servicing industries with sand, cement, and other dense materials.
Below is a pic of the real thing. It is a
pic. This one is in the WM Speed lettering paint scheme,
other runs of Bowser kit better approximates.
Below is one of my Bowser
PS small covered hoppers.
These cars were old by the time the Chessie Era started, so make
weather them lots to show those years of service. These
sand and cement spilled all over them. Weather them with
tan to show this.
