| 1036 To HPS. {Horace Percy Smith - Experimental Factory Mgr} Rm {William Robotham - Chief Engineer} /CTS. {C. Trot Salt - Carburation} 3/JH.18.12.39. INDUCTION PIPES. You have recently supplied an induction pipe for trial on the Ripple, the bore of which had been reduced by inserting sheet lead into the core-box during casting. This has shown considerable improvement over the previous type. We now wish to carry this a stage further, so will you please produce two further pipes having a bore 1.250 dia. by the same method. The piece No. is EW.1557. O {Mr Oldham} /N.52469. Rm {William Robotham - Chief Engineer} /CTS. {C. Trot Salt - Carburation} | ||
