Tony,
Zenith were a manufacturer of small electric motors in the post war era. Rovex seeing the future bought the company to produce the motors for its Model car and train planned projects. They made a vast variety of different motors , but you have just stated a zenith motor, not its type. Refering to Pat Hammonds book, Triang Railways Volume 1, there is a lot of detail about Zenith products and its history, with several illustrations of some of the types made by them. Also ebay very often has Zenith motors up for auction in the "trains/model railways" section.
