| RE- E.BY. ) FROM R.{Sir Henry Royce} HS.{Lord Ernest Hives - Chair} ) R2/413.8.32. C- to SGY- WOP- DA{Bernard Day - Chassis Design}- HPM- 1932 AUG PEREGRINE. x4027. The Peregrine controls worked extremely badly when I saw the car - practically all that has to be operated by the fingers.) In this respect I believe we have written before hoping that the spring pressure would be reduced very considerably, and that the rating of the springs would not much exceed [strikethrough]20lbs[/strikethrough] 50% through the range that they have to be operated. Regarding the change speed lever, H.S. pointed out that this bound in the bearings, probably through deflection and insufficient clearance, but since it once happened it might happen again, so we have entirely altered the arrangement, which we think has produced a stronger, less expensive scheme, in which the fault should not possibly be capable of appearing. We have shewn the shaft quite parallel, and the maximum diameter permissible by the space occupied. It is supposed to be made from a piece of ordinary bar, and the pendulum lever A.{Mr Adams} in the gearbox layshaft firmly pressed on and taper pinned, possibly with the end of the shaft knurled; this has been found inexpensive and efficient in the shock damper levers.
