Hollingworth} c. By/Ald.{F. Allwood - Experimental Design} Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell}6/MH.{M. Huckerby}3.6.39. In conjunction with the trial of the I/C shaft running direct in the crankcase, some wear has developed on the end thrust plunger, (EXS.769). This is in BZ/PC. and to try and obviate this trouble we should like you to make two plungers in S/EN. with hardened finish. Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell} | ||
