| 1158 Rm {William Robotham - Chief Engineer} Please reply AH Managing Director Rolls Royce Motors. 98 Knightthorpe Rd, Loughborough Leicestershire Nov 22nd '39 Dear Sir I should like to bring to your notice a new type of car heater which has recently been patented by my brother Mr. W. D. {John DeLooze - Company Secretary} Picetto of Brighton. This is an entirely new system which entails no drain on batterys, gives off no fumes and once fitted is free of any running cost whatsoever. In a few minutes from starting the engine the radiators heated by this system become quite hot and will remain at a good temperature for over an hour after stopping. | ||
