| To RM.{William Robotham - Chief Engineer} C. EFC. Deverley. RE 20 H.P. CHASSIS - FRONT AXLE. X.3482 B X.3516 4263 Please receive herewith two blue prints of:- N.203 - Top Steering Lever. N.237 - Cap Nut for Cross Steering Lever. N.282 - Wheel Disc. N.283 - Nut for Pivot Axle Pin. With reference to N.282, this differs from the standard Mitchelin wheel in the dimater of the inner hole, and the centres of the attachment bolts. We have already written to the Mitchelin Tyre Co., anking them if they were prepared to make us wheels of this non-standard size but they did not seem keen on the job. We should be glad if you could ascertain whether it is possible to make them ourselves or to get them made out, either partially or entirely. DA.{Bernard Day - Chassis Design} | ||
