| contd :- -3- Attached are ratings of the two couplings we are trying and details of the Chrysler spring drive which you will see are almost a year old. We cannot help feeling there is something in it, but to knock the peak off the indicator diagram it looks as if about 15° spring controlled movement is wanted. Please return Chrysler details for our file. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
