| To Sg. {Arthur F. Sidgreaves - MD} from Hs {Lord Ernest Hives - Chair} /Lid. {A. J. Lidsey} c. Wor. {Arthur Wormald - General Works Manager} E. {Mr Elliott - Chief Engineer} c. Da. {Bernard Day - Chassis Design} By. {R.W. Bailey - Chief Engineer} X311 Hs {Lord Ernest Hives - Chair} /Lid. {A. J. Lidsey} 10/KT.21.7.33. X 20 80 D.W.S. JACKS AND 20/25 HP CARS. We should estimate that at least 25% of the 20/25 HP. cars which we turn out now are fitted at the coachbuilders with D.W.S. Jacks. The customer pays £10.0.0 plus £1. fitting charge for this and in addition is of course landed with the standard jack as supplied with the car, the cost of which is to us 19/6d. At the request of the D.W.S. people we have modified our rear spring plate so that the jacks can be more easily fitted; this modification will appear on all 20/25 HP. cars. The present car, therefore, can be fitted with D.W.S. jacks without any further modifications. We are trying out a sample set of a lightened type of D.W.S. jack which are suitable for the 20/25 HP. car. These appear to be quite satisfactory. We understand quite unofficially that the price of these jacks in quantity would be very much less than what we pay for the 40/50 HP. jack, and is so low that it would appear to be well worth while considering the possibility of standard-ising them on this car. Actually it is very little easier to jack up the rear of a modern 20/25 car than a Phantom II when using the ordinary screw jack, and we are of course faced with the fact that D.W.S. jacks appear as a standard fitting on an increasing number of moderate priced cars.
