| X5783dr To Hm{Capt. W. Hallam - Head Repairs}/NRC.{N. R. Chandler} from EFC. EFC8/T6.7.27. BATTERY IGNITION H.T. ROTOSS. X8783dr You have to-day handed to us a case of failure of the bakelite body of a battery ignition H.T. rotor by tracking. You also handed to us a similar case sometime ago. We have no record or recollection of any other cases of failure on customers' cars than these two, but if you have information of any other cases, we think this should be passed on to us. EFC. | ||
