| 328 HPS.{Horace Percy Smith - Experimental Factory Mgr} from Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} Rm{William Robotham - Chief Engineer}/Gry{Shadwell Grylls}1/R.13.11.36. P.III GEARBOXES. Further to our Rm{William Robotham - Chief Engineer}7/GR.{George Ratcliffe}5.11.36. re building of two more gearboxes, we would prefer them to have standard front halves instead of the wide feet variety. This enables us to use any parts desired inside, and also the standard change speed mechanism. Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} | ||
