Cont'd.{John DeLooze - Company Secretary} (6) The side spare wheel is raised 2" above B.3. by lengthening the tubular arm. (7) A design is needed for the Rolls-Royce bonnet. (8) The exhaust system is that of B.50 with the exception that the exhaust silencer is 3" longer than B.50 ( 9" longer than B.3) and the B.50 tail pipe is lengthened to deal with the increased body overhang. (9) The propeller shaft is that for B.3, with the semi floating axle, but the intermediate shaft behind the gearbox is lengthened 9" above that of B.3. The centre of the forward bearing of the propeller shaft is lower due to this latter increase in length. (10) We suggest that built in hydraulic jacks are needed on this car. As far as we have been able to ascertain the body in all its interior dimensions is the same as the Six Light Enclosed Limousine which Sales are proposing to build at Messrs. Park Ward & Co. for the Wraith 3. As we already know this is a very much bigger body than we have ever before put behind this size of engine. The frontal appearance will be almost exactly that of Wraith 3 and it will not be perceived that the radiator is 1.800" further forward of the front wheels. The wheelbase is 11' 1" as against the Wraith 3, 11' 4". The overall head room inside the body for the same height of car is appreciably greater on the Silver Wraith than Wraith 3. For the same interior head room the car is approximately 1" lower. The ground clearance with 16 x 5" rims and 7½" tyres is 4¼" under the clutch casing on full four wheel bump. On Wraith 3 this is 5.150". As soon as we have hydraulic brakes we can raise the front of the car 1" by merely altering the yoke piece, and if we wish to raise the car before then, we can do so by increasing the downward inclination of the front triangular levers.
