| X8692 By.{R.W. Bailey - Chief Engineer} from EFC. c. By/RD. EFC3/AD29.5.29. X.8692. BATTERY IGNITION ON 10,000 MILE TEST CHASSIS 22-EX. Referring to the paragraph of Mr.Hancock's report dated 2.5.29 dealing with the contact breaker points and reading as follows :- "The tungsten contacts caused misfires after a milage of 5,000 due to the points being burnt. The contact points had been incorrectly set in the first instance, full surface of contacts not being made. We have had similar settings without the points becoming burnt. We returned the contacts to Derby and received a reply see EFC/WD{Mr Wood/Mr Whitehead}52 and EFC1/T11.4.29". Please find attached copy of my assistant's report WD{Mr Wood/Mr Whitehead}52 dealing with the result and inspection of this contact breaker after it was returned to us. We wish to emphasise the great importance on production, of the correct opposition and bedding of the contact points as dealt with in the first two lines of our specification of production inspection and test of this unit.
