| BY.{R.W. Bailey - Chief Engineer} FROM DA.{Bernard Day - Chassis Design} [BY.{R.W. Bailey - Chief Engineer} is struck through] Copy to BI. HS.{Lord Ernest Hives - Chair} [BI. is struck through] ORIGINAL DA{Bernard Day - Chassis Design}2/M14.11.28. 'SS{S. Smith}' - TWO WHEELS ONLY AT REAR. X7810 [struck through] Y5810 X 7600 In view of the pressure on the coachwork dept. we should be very much obliged if Derby could set out this arrangement for 'SS{S. Smith}', as we think the information we have supplied will enable them to do. We have today sent off N. scheme 2760. shewing the arrangement for India, and in N. scheme 2732. you have the existing arrangement on 'SS{S. Smith}'. We suggest that you should use the same size central bolt increased in length only as on N. scheme 2760. The tubes of the supporting triangle should be increased from .875" to 1", and of course the tube in front of the wheel carrier should be 1¼" in diameter. The tubes and fittings carrying the number plate can be the same. The dummy hubs are of course scaled up to correspond with the wheels. If Derby could set this out and send us the result we think it would enable us to get this carrier for 'SS{S. Smith}' going more quickly. We believe you understand that R.{Sir Henry Royce} has agreed to N. scheme 2732. on his car - that is, 18-EX. the 1st. 'SS{S. Smith}' - but the scheme similar to N. scheme 2760. will be required on some of the following 'SS{S. Smith}' cars. DA.{Bernard Day - Chassis Design} | ||
