DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork}2/M.13.9.32. We have not yet had sufficient experience with Peregrine to make a decision as to whether we shall have to go to the 17" rim and 6" tyre. We have presumed that all the first six cars are to have 18" wheels and have obtained wheels of this size for them. Ha/Lid.{A. J. Lidsey} | ||
