| Y4241 To Da.{Bernard Day - Chassis Design} from E.{Mr Elliott - Chief Engineer} c. to CJ. Wor.{Arthur Wormald - General Works Manager} c. to BY.{R.W. Bailey - Chief Engineer} Hs.{Lord Ernest Hives - Chair} c. to EP.{G. Eric Platford - Chief Quality Engineer} E1/M16.6.22. GOSHAWK BONNET AND RADIATOR. X.4240. E.4241. We send herewith drawing No.LeC.1595 shewing the proposed modification to the dimensions of the bonnet and radiator. A copy of this drawing has been sent to Sales for their comments. The dotted lines on the drawing represent the existing bonnet and radiator. It is proposed to make the new radiator 1" narrower and 1" higher, at the same time making the top tank .5" deeper that is to say, the top line of the matrix will only be .5" higher. The bonnet at the dashboard end is 1/4" higher, and the slope of the side hinge has been reduced to 1/4". The appearance of the radiator will be altered by the fact that it is narrower and higher, and also by the fact that the top tank is deeper. The same angle for the shoulders has been retained, and the radius on the edges of the tank has been increased from .187 to .250. E.{Mr Elliott - Chief Engineer} | ||
