Rm{William Robotham - Chief Engineer}/Wym.{G. Harold Whyman - Experimental Manager} Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev. Engineer}2/MH.{M. Huckerby}31.1.38. NEEDLE BEARING FOR WRAITH FRONT AXLE PIVOTS. We wish to fit PD.97, needle roller lower pivot bearing, to two of our experimental cars, 24.G.VI and 29.G.VI, as soon as possible. We have ordered from Hoffmanns 8 sets of outer races, GW.1961, complete with needles and two sets have already been received. All our experimental chassis except 26.G.VI. have yokes bored for oversize pivot pins so that it will be necessary to fit new yokes in order to try the needle bearings. We suggest that our oversize yokes should be exchanged for correct yokes intended for the six production chassis. Will you please make two sets of parts as soon as possible.
