| X7653B BY.{R.W. Bailey - Chief Engineer} FROM E.{Mr Elliott - Chief Engineer} E1/M14.7.28. Copy to RJ. " HS.{Lord Ernest Hives - Chair} " EPC. EAC.10. SEQUENCE STARTER. We send herewith drawing LeC.2572., shewing the main switch for the above. We think it advisable to make up the first models without bakelite mouldings for the base and cover. The former piece should be made out of a solid block of insulation of some sort to begin with, and the cover can be dispensed with entirely until the device has progressed up to the point when it is likely to be standardised.
