| TO EFC. FROM E.{Mr Elliott - Chief Engineer} c.c to BJ. ORIGINAL re. BATTERY IGNITION. E1/M4.2.27. 2 X.8692 X4/6/52 We have telegraphed to BY.{R.W. Bailey - Chief Engineer} even date for a print of the battery ignition Contact arm with off-set pad as we wish to go over the design, and also set out the velocity curve of the make and break. We will send you as soon as possible a design for the disc type H.T. rotor, but this has to be squeezed in with the remaining aero work on RR.F.10. E.{Mr Elliott - Chief Engineer} [Signature] | ||
