| Roy.{Sir Henry Royce} From He/Wst. Ha/Wst.1/MA.25.6.34. FERRANTI AMMETERS. Answering your Roy.{Sir Henry Royce}5/MG.20.6.34., we are not ready to make a report on Ferranti ammeters as we are awaiting completion of road tests. We should be glad if you could inform us what extra cost, if any, will be involved in the standardisation of this Ferranti ammeter as compared with the Weston and the Lucas damped ammeter.
