Thanks Colin!

I also looked up the body type, the 4K1 was a "special steel Telephone (Signals Line Construction) body (...) similar to the standard commercial vehicles used for telephone construction work":




I also compared it with the body on the US Signal Corps' model K42 or K43 (G7173) which is of similar construction but shorter. So the Chevrolet C60S shown above as assembled by Mr Dieffenbach, was the result of some artistic license. That body was put back on the type of chassis it was originally fitted to.
