For obvious reasons, the Silver Ripple is going to be heavy for the duty which it has to perform. This is because it is built up of Senior Rationalised parts which have also to be used on a 5 1/2-litre 7-seater limousine. The first Silver Ripple specification has been evolved with the object of producing a car with the minimum amount of 'unknowns'. This is essential if we are to give the planning people an opportunity to get going immediately after the war. A second Silver Ripple specification is projected which will use as many of the Myth parts as can be tested in a short space of time and also include any lightening of existing components in so far as this can be done without affecting rationalisation to a serious extent. As an example, the brake drums can obviously have a considerable amount of material removed from the external diameter and still have adequate heat dissipating capacity for the 16 h.p. engine. I should like all concerned to give me their suggestions as to what can be done to enable us to complete the Silver Ripple 2. specification. Attached is a copy of a note from Cr.{Mr Cra???ster / Mr Chichester} which gives some sort of a target.
