| 49910 Mem. Mr. [Illegible] Mr. Hivesth. Mr. Hs.{Lord Ernest Hives - Chair} BY24/H.{Arthur M. Hanbury - Head Complaints} 27.5. 24. The Face Cams operating the Servo mechanism still appear from one of Hs{Lord Ernest Hives - Chair}' reports to be in doubt from the point of view as to what is the best angle to adopt. The angle instructed originally was 45°. Hs.{Lord Ernest Hives - Chair} is inclined to think this gives too easy braking, and would try 55°. I think we should not produce any of these parts at the moment, but await further information from Hs{Lord Ernest Hives - Chair}, either confirming the 45° or modifying the angle in question to 55°.
