This box set would have been fun toplay with. The trailers interchange with the cab to make five different trucks. All the assembly is done with nuts and a wrench that are included. The assembled cab and trailer are 12″ long and 2.75″ wide. This example is not NOS but likely only the base cab and trailer were removed from the box the trailers are still attahed to the cardboard backing. Produced sometime after 1953.
