| R.R. 255a (100 T) S.H. 89. 22-7-20) G 2769 X4244 To CJ. from R.{Sir Henry Royce} Extract from R4/G17.11.20. X.4219. RE SMALL R.R. CHASSIS. X.4231/2. Oil Pump, dynamo and water pump driven from camshaft or camshaft gear wheel. (The text 'camshaft or camshaft gear wheel.' is struck through) X.4250. X.4275. Such a small engine permits of a starter motor of a small size, and only a single train of gear, and the shaft with spiral keys. (The text 'and the shaft with spiral keys.' is struck through) X.4228. (This reference number is struck through) No governor. X.4244. The clutch will be multiple plate, but direct operated like the Northcliffe clutch, and not like the "Goshawk" clutch, which is lever operated, and is considered too expensive. | ||
