| - 2 - Cont'd.{John DeLooze - Company Secretary} we have made a better motor car for several items we can measure, but we are anxious to have the opinion of someone who has been using the Wraith, to ensure that we have not lost any of the desirable qualities which cannot be measured. The B.50 gear ratio is 10% higher than the Wraith. This is not necessarily intentional but we have not a supply of the correct rear axle gears. We append a comparative list of body dimensions, which should be correct unless your Wraith body is in some way special. The feature we like best about the B.50 body is the increased luggage accomodation. Do not take any notice of the instrument board or top of the column. These can be exactly like Wraith or any other arrangement which is considered desirable. We have not yet finalised on the instrument arrangement for the rationalised range of cars. Rm.{William Robotham - Chief Engineer} Footnote. 3.B.50. speedometer is accurate. The standard Wraith instrument reads 80 m.p.h. when the car is doing 76. | ||
