| RHC.{R. H. Coverley - Production Engineer} EFC. X76555 BY/RD8/N.10.5.29. Push Button Switch - Section 8240 - For 23-EX. X-6441 7655 Owing to push button switch D.72088 being unsatisfactory for production it becomes necessary to fit the above car with a switch as near to production as possible, and as the dies are not yet ready to enable you to have a switch to the production Part List, we should use what material we have available from some previous instruction some long time ago, and from what I have seen of this material in Mr Brock's Dept. it looks as though we shall easily be able to produce one switch; therefore, will you please instruct for a push button switch to LOP D.71122 to be built up. We attach hereto blueprint D.72254 - Face plate which should be fitted to this switch in order to match the various instruments as shown on N.sch.2836. BY/RD. | ||
