"Designed and Manufactured by the Kalamazoo Manufacturing Company, Kalamazoo, Michigan", and contained their company logo. 

Hagerty says instead, it was designed in a collaborative effort by the Disney organization, New York City planner Robert Moses, and the design firm established by Harley Earl. I can certainly believe Disney imagineers made the design

 The Escorters also sported a plaque on the dash, behind the steering column, which stated "Manufactured by Kalamazoo Manufacturing Co. for Greyhound at the World's Fair 1964-1965". This plaque also contained the Serial and Engine numbers. 

 Unfortunately, Kalamazoo ceased operation in the mid 1980's after over 100 years in business. Their primary interest was the manufacture of railroad and off-road utility vehicles.

  Escorters had ’63 Plymouth tail light assemblies.
