I have received your memo EP{G. Eric Platford - Chief Quality Engineer}7/H24.4.28 and note the opinion of everyone regarding them. As I wrote originally, 87-RF has been mostly used abroad, whereas 61-RF has been entirely used in England and mostly about London, so that it can be presumed that the experience with 87-RF in general is at higher speeds than that of 61-RF. The fact remains that in its general use the whole suspension of 87-RF has given more satisfaction that that of 61-RF. I feel myself that there is some difference which is hard to explain, but it certainly seemed to me that if one wheel met an obstruction in 87-RF there was more feeling of a general movement of the whole body and frame, whereas in 61-RF there appeared to be more local movement at the particular wheel concerned. It was for this reason that it was thought advisable to have all the springs of 61-RF taken apart and thoroughly greased also dressed if necessary and it is hoped that this will be done before the car is returned from ?. In the meantime we will go very closely into the question of the upholstery on the return of the car - perhaps it will be possible to do something in this respect. I do not think there is any occasion to incur any expense in dealing with the question of slight piston knocks in 87-RF when starting up from cold and the car must not be delayed for this matter.
