| RHC.{R. H. Coverley - Production Engineer} from EPC. c.c. Ha/AJL. X2498 EPC1/A36.7.29. X.3498. FERRANTI AMMETER X4622 We are anxious to get more mileage on the Ferranti ammeter at present on 9-X. It appears that 12-X runs a bigger mileage, and as this is the only car on which the instrument can be fitted, we should be pleased if you will arrange to effect an exchange of the ammeters on these two chassis, the one on 12-X being a standard Elliott instrument.
