view of the proliferation of new models and their shorter life over which to recover their design development and production costs together with the potential saving in transport costs it had been decided to gradually remove the manufacture of engines from Coventry to Guildford. A new building for the purpose was being completed in Guildford and the change would be complete within twelve months. A few months later it was announced that Dennis would fit diesel engines made by Armstrong-Saurer Commercial Vehicles of Newcastle upon Tyne, Swiss Saurer products made under licence by Armstrong Whitworth. Dennis would have sole rights for the fitting of these products to passenger vehicles. White and Poppe ceased operations on 28 March 1933. Required plant and machinery of a combined weight of more than 2000 tons was moved unpacked from Coventry to Guildford by road. Each machine was picked up from its old position and deposited in its new position at Guildford under the guidance of Erling Poppe at Guildford. This unpacked move of plant was reported as widely as possible because Dennis Brothers wanted it to be "a testimonial to the efficiency of road transport". Liquidation Dennis Brothers voluntarily liquidated White and Poppe, i.e. turned their assets into cash, on 28 March 1933. In the absence of any buyer they took ownership of the premises and eventually sold the Holbrook Lane Foleshill Coventry premises and plant and machinery not required in Guildford in May 1933. Much of the factory was taken over by SS Cars Ltd which later changed its name to Jaguar Cars Limited.
