| S/W. COPY Hn{F. C. Honeyman - Retail orders}25/AH.2.11.38. Wraith Road Springs: ------------------ With further reference to ROY{Sir Henry Royce}/Les.10/B.10.10.38., we have now weighed a fairly representative batch of completed Wraith cars so that we know rather more about body weights now than when in Hn{F. C. Honeyman - Retail orders}7/AH.7.5.38 we gave Rm.{William Robotham - Chief Engineer} estimated weights. From the weights we have obtained of completed cars, we find:- (a) Our Standard 7-Seater Enclosed Limousine or Pullman averages 13 cwt. (b) Our Standard 5-Seater Four-light Saloon weighs 12¼ cwt. (c) Our Standard 5-Seater Four-light Saloon with division weighs 12¾ cwt. We reckon that about 25% of 'B' series chassis may have our Standard 7-Seater Enclosed Limousine Bodies, 20% our Standard 5-Seater Saloons and 15% our Standard 5-Seater Saloons with divisions. Then we estimate there will be 20% of the total mounted with 5-Seater Bodies weighing 13/13½ cwt. 10% of the total mounted with 5-Seater Bodies weighing about 14 cwt. and the balance of 10% will be mounted with 7-Seater Bodies weighing about 14½ cwt. There will, of course, be isolated bodies weighing still more, perhaps as much as 15 cwt or 15½ cwt, but we are doing our very utmost to keep coachbuilders down to the weights of our Standard Bodies and hope that as a result bodies weighing more than 14 cwt or 14½ cwt will be very rare. Of course, you will bear in mind that about 10% of the output may be exported. We do not know whether this will make any difference to the springs. Hn.{F. C.
