| Y457. EP{G. Eric Platford - Chief Quality Engineer}3/H20.3.30. x 457. x 5380. x 5280. FRAME & RADIATOR JELLYING - 20-HP. With reference to your report on the above, Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}6/MJ.12.3.30. and as discussed with you today I am of the opinion that at the same time as we are tackling the Phantom II car in this respect, we should also consider similarly tackling the 20-HP.chassis. In our experience of testing new complete finished cars, the amount of radiator movement varies on the 20-HP. chassis and some are rather poor in this respect and we consider as bad as some of the Phantom II. We are not quite sure that the 20-HP. has the same characteristics as the Phantom II. The period, if anything, appeared to be slower and at slower car speed, about 35 m.p.h. over rough roads being its worst condition; The trouble with the 20-HP. car is that there is a considerable amount of wear and tear and knocking taking place with the bonnet and the wear and tear on these parts causes excessive damage to the radiator and dash board, bonnet fittings, strips etc. Also there seems to be a considerable amount of wear and strain taking place on the front wings, head lamps etc. This point We found is again confirmed as being a trouble on the 20-HP. car now running 10,000 mile test in France.
