This is a very accurate model of a Roger Bros. cable operated removable gooseneck trailer of about 1950. Rather than using a hydraulic ram to raise and lower the trailer bed during the unloading process, the ram was operated by a cable controlled by the tractor's winch.

The "geep dolly" or as Rogers calls it, a gooseneck dolly, is the same as that used in the Sheepscot kits 95046, 95047, 95048, and 95049 cast metal lowbed kits.
