In the goode old daze, I bought my first S scale kit in 1965.? The advertisement said, "Trucks included".? When the box arrived, I got my first taste of S scale.? The trucks were kits themselves and the parts had a lot of flash.? With enthusiasm, I got out my trusty file, removed the flash and built the kit.? And the memory lingers on.
Shown in the photo are some castings of the day.? I believe they were called Kinsman trucks, or Northeastern trucks, or Sandusky trucks or Culp Brother's trucks or who knows what back then.? But the castings were all the same regardless of the name du jour.
If this sort of history appeals to you, the price is almost right.? Make your best reasonable offer for six pair of castings and see what happens.? If nothing else, they could be used as loads in gondola cars or scattered around the yard area as scenic details.
