| BY.{R.W. Bailey - Chief Engineer} FROM DA.{Bernard Day - Chassis Design} C. to HS.{Lord Ernest Hives - Chair} SECRET. DA{Bernard Day - Chassis Design}2/M28.3.29. SS.{S. Smith} EXHAUST SYSTEM. CUTOUT OPERATION ETC. X7230 X7490 Herewith are N. schemes 2866/7., shewing the adaptation of the cutout, silencer suspension, heat shield, etc. to the tubular members. We suggest that the 3" dia. member instead of being 18" from the 2 1/2" dia. one, should be 17 1/2", which means simply shortening the tubular part without affecting anything else. We have also modified the set of the 3" member in the centre. With these drawings we think we have completely instructed SS.{S. Smith} for production. DA.{Bernard Day - Chassis Design} | ||
