Barber S-2 50 ton truck, with early covered roller bearings.  HO scale.

It is difficult to provide a list of exactly which cars used these trucks due to diagrams not specifying the style of Timken bearings used.  One example is WM fishbelly hoppers 14851-14900 (Bowser model).

Package contents: (1) pair of ready-to-run trucks with semi-scale (code 88) nickel silver wheelsets and brake detail.
