| Hs{Lord Ernest Hives - Chair}/Wst. - from Roy.{Sir Henry Royce} 83497 WST ROY{Sir Henry Royce}/S2/P.29.1.34. Please advise as to the possibility of standardising the Ferranti Ammeter for 40/50-HP Chassis 'S2' Series and Bentley 'B' Series, in place of present Weston Ammeter, which I understand is giving trouble.
