[STAMP: RECEIVED 14 APR 1931] SHOCK DAMPERS. The position in regard to the above is as follows :- 1/- We have completed and issued experimentally only a shock damper to drawing F.83611 suitable for the rear of both L.H. and R.H. Phan. 11 chassis. 2/- We have issued experimentally the scheme shown on N. Sch. 3244, which introduces an oil pipe from the low pressure valve to pour oil over the working end of the connection. 3/- We are producing designs of a similar type on the front damper of the 20/25 HP., the same castings and pieces can be used with the exception of the lever and connecting link, which, however, follows the design for similar parts shown on F.83611. The Works have been told to go slow on all the various parts, but we cannot stop work on any of these dampers until we have something which will definitely replace them in production. We anticipate completing the 20/25 HP. modifications this week. 134 [handwritten] BY.{R.W. Bailey - Chief Engineer} | ||
