| 83409. To Roy.{Sir Henry Royce} From Hs{Lord Ernest Hives - Chair}/GWH.{George W. Hancock - Head Chateauroux} c. to By.{R.W. Bailey - Chief Engineer} c. to E.{Mr Elliott - Chief Engineer} Hs{Lord Ernest Hives - Chair}/GWH.{George W. Hancock - Head Chateauroux}1/MA.9. 4. 32. Re. SERVO FABRICS. We have now completed our tests with the two samples of servo discs. The discs treated with the W method we find to be definitely inferior for the servo to those with the lesser dope. Will you therefore instruct the works to use fabrics with the lesser dope, and any further orders should be this material. The present stock should be sent back to be treated.
