| Hs.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} c. BJ. Wor.{Arthur Wormald - General Works Manager} BY.{R.W. Bailey - Chief Engineer} E.{Mr Elliott - Chief Engineer} X3587 R2/M7.9.27. IMPROVEMENTS TO 20 HP. STARTER. X.5650. X.3887. I understand there are two stages in these improvements, the first making the best of the present Bijur, namely, modifications to the present scheme, then the second modification where the starter pinion is altered to a more rational R-R scheme which may function extremely well, or extremely badly, but if it functions well, it should be consistent, more understandable, and more reliable.
