DA.{Bernard Day - Chassis Design}1/M25.10.29. SPORTS PHANTOM REAR AXLE. X. 7350 X. 2066 Herewith we send N. scheme 2972 shewing the 13/41 pair of hypoid gears which it was decided on Wednesday were those required for the sports Phantom. Naturally it will be necessary to leave the details to the gear makers, but we consider there should be no difficulty in getting this ratio into the present box. DA.{Bernard Day - Chassis Design} | ||
