To EFC. from R.{Sir Henry Royce} Copy to CJ. " " C. ORIGINAL. X.1114 RE 1/2 WATT LAMPS. D 9 JUN 1920 R9/G8/6/20. RECEIVED 4 The B.T.H. have sent us a further supply of 12 volt 24 watt 1/2 watt lamps. We regret to say that after giving a very brilliant light on the 12 volt circuit for a short time the only one that has been in use for a few hours has failed. We do not consider they have touched the faulty spot. R.{Sir Henry Royce} R'R' S32D (500 D) (R'D' 408 RC{R. Childs}-4-15) Bur' Streets | ||
