The Kinsman reefer kits did not include trucks nor couplers. Kinsman did have trucks available separately, but they eventually discontinued them. After that, John Bortz, under the name Delaware Valley Kits, manufactured and sold the trucks for these cars. Scenery Unlimited eventually re-released some of these kits in the late-1970s.
