X3362 COPY R9/G8.6.20. To EFC. from R.{Sir Henry Royce} Copy to CJ. C. --- X.1114. RE 1/2 WATT LAMPS. X3362 --- The B.T.H. have sent us a further supply of 12 volt 24 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} [Handwritten note]: A correction '1/2 watt' with a caret is written above the word 'watt' in the first sentence of the main body. | ||
