| HS.{Lord Ernest Hives - Chair} FROM R.{Sir Henry Royce} C to BJ. WOR.{Arthur Wormald - General Works Manager} RG.{Mr Rowledge} [Strikethrough] S ORIGINAL STEERING BOX EXPERIMENTS - LUBRICATING OILS. -Y8430 X1583 X1588 Y967 The superiority of Price's Amber Gear oil is somewhat of a mystery unless a compound oil, or there is much difference in mineral oils from different sources - i.e. Price's probably is an oil from the East, near or far, whereas Springfield oil is U.S.A. source (West.) Your tests suggest that we might be able to arrange some apparatus that would give readings of the relative value of oil under this slow speed, heavy load, condition of working. I will send you a few sketches later. In the meantime I should be pleased if you will include in your tests other Wakefield oils, such as Castrol R.{Sir Henry Royce}, and Castrol XL., together with a gear oil that Wakefield's recommend, and also obtain if possible from Price's the information as to whether their amber gear oil is a pure mineral oil, or a mineral oil compounded with some vegetable or animal fats. I understand this amber gear oil is that which we are using and recommending for gearboxes, back axles, and all the Enot greaser points. In other words practically everything except the engine proper, magneto, and such like requiring thin oil. R.{Sir Henry Royce} | ||
