ASF A-3 70 ton truck, with early covered roller bearings.  HO scale.

This particular truck was modeled as an accurate replacement for recent SFRD mechanical refrigerators.  It is also accurate for some PRR prototypes, albeit with different bearing brands.  Some PRR H30As, all H33s, and some F39s were equipped with trucks like this.  There certainly would have been other roads using this truck as well.

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