| COPY. BJ. BY15/H9/7/25 COMPARISON OF RADIATORS FOR 'V' and 'W' SERIES RESPECTIVELY. Referring to our conversation on the telephone this afternoon, the facts of the case are that R's criticisms which I referred to in my memo BY10/H9/7/25 were expressed to the Experimental man who took down the 'W' Series chassis for R's consideration and criticisms. Mr. Royce, when he saw the scheme, certainly got the impression that the 'W' Series radiator as proposed made the front of the car look big, and, as he expressed it 'bloated'. A memo from Da.{Bernard Day - Chassis Design} we have received to-day, which I read to you, evidently expresses R's views, as it covers the same ground. They are under the impression that a second car, 9-PK, fitted with a 'V' Series radiator having a matrix 1 in. higher than standard did not convey to one the same impression of height and larger dimensions. In thinking the matter over, it is evident that the different appearance from a 'V' Series 1 in. higher and a 'W' Series is that the 'W' Series, in following the inclination of the bonnet at the sides and top, has a wider appearance, which as a matter of fact the increased in width at the back of the radiator as compared with the front is 1.375 in., the increased height at the back of the radiator as compared with the front is approximately .250 in. In addition to the foregoing, R.{Sir Henry Royce} took exception to the method of operating the shutters which was proposed for 'W' Series. In the scheme he criticises the control is at the top and the connection for the louvres operating the shutters run through a kind of tunnel, the tunnel being produced in the form of a flattened tube of fairly robust dimensions which is worked into the matrix at that point. In the old scheme, the shutter control went straight to the back of the radiator, passed around the back of the radiator and the controls on the shutter were operated by couplings passing beneath the bottom tank. So far as our readiness to issue material at the Works is concerned, we can issue:- a/- 'W' Series as originally proposed, if you succeed in getting R's consent to same, and agree to it yourselves. | ||
