In my grab bag there is an unlettered short Ulrich cast metal HO "piggyback" flat car. Without any real thought, I have always presumed that it was an SP prototype, but in truth, do not really know. Does anyone know anything about this ancient model?

Stan Rydarowicz sells very attractive finely-built lasercut "fences" that converts a series of Bowser PRR flats for early piggyback use.
