| To EFC. from R.{Sir Henry Royce} Copy to CJ. " " HL. (struck through) " " WD.{Mr Wood/Mr Whitehead} (struck through) ORIGINAL (stamp) RECEIVED (circular stamp with clock face) X. 1699 RE HIGH CONDUCTING STUDS AND BOLTS. RECEIVED (stamp) Will you kindly find out whether it is practicable to obtain for our electrical manufacturing department, rods of silicon bronze, hard drawn copper, or any other metal or alloy of high conductivity suitable for making switch contacts and connections, i.e. to turn and thread. It should have a high yield point, and at the same time should not be brittle. Will you please see Mr. Whitehead and Mr. Hall as to what is available.
