Abbreviation: cav
Summary:

Info Jeremy Stevens, Prestolite Electric Ltd. (ex CAV:
The company C.A. Vandervell & Co. Ltd. in Acton (West London) was founded by Charles Anthony Vandervell (CAV) in 1892 and moved to Warple Way, Acton London W3 in 1904. It's brand name was CAV (and others). In 1926 the company merged with Joseph Lucas and Rotax.

In 1932 the association with Robert Bosch was formed. I am not sure when Bosch took over Ideal but it must have been during the early 1930s about the time CAV became involved. This partnership was, of course, terminated abruptly in 1939. The company later became the name Prestolite Electric Ltd and is moving out of Acton (West London) in 2005.

History:
Mr. Vandervell was a true entrepreneur and was involved with all sorts of money making projects. Before the Blue-Spot radio British designed radios were made under the CAV and CAV-Rotax brands. We have found two of these "Baby Grand" TRF receivers - see photographs. Both sets are now saved (Leon Crampin). Only the drawings for the W400 still exist. CAV also made loudspeakers. See the attached photo taken in the factory.

From about 1935 onwards CAV concentrated on its core business of commercial vehicle equipment, diesel fuel injection, starters, generators and switchgear.
