| BY.{R.W. Bailey - Chief Engineer} FROM E.{Mr Elliott - Chief Engineer} X/7460 E2/M19.5.31. C. to SG.{Arthur F. Sidgreaves - MD} WOR.{Arthur Wormald - General Works Manager} HS.{Lord Ernest Hives - Chair} P. 2. PETROL PUMP OPERATING MECHANISM. We send you herewith LeC. 2909. shewing the above. This matches up with the design for the petrol pump itself posted to you on Sat. als- last. In connection with this latter scheme we would point out that for the existing engine it is necessary to use an hexagonally shaped pumping diaphragm, but that for the future work a cast pocket can be formed as indicated in the front cylinder block to enable the standard A.C. diaphragm to be used.
