| X350 Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} E.7/HP.12.11.35. Phantom 3 Steering. Referring to the above, it would be a great advantage if we could use the roller cage F.87751, and this will almost go over the diameter of rocker shaft shown on HS.{Lord Ernest Hives - Chair}2071. We should, therefore, like you to grind one of your rocker shafts of this number down to 1.3 diameter, and try it on a car. If the result is favourable we shall be able to use the desired rocker cage. E.{Mr Elliott - Chief Engineer} | ||
