| To HPS.{Horace Percy Smith - Experimental Factory Mgr} from Rm{William Robotham - Chief Engineer}/Std. 1328 Rm{William Robotham - Chief Engineer}/Std.3/AP.25.6.37 We send you herewith Rm.{William Robotham - Chief Engineer}401 which shows a modification to Bentley thermostat casing EB.3321 (detailed for scheme LeC.5655). You have ordered four sets of parts to this scheme, but only one thermostat casing to EB.3321 has been machined as yet. Will you please modify the other three casings as shown on Rm.{William Robotham - Chief Engineer}401 - the only difference is that the bore of the valve guide is 1.380 + 3 instead of 1.400 + 5 - and let us have one of the finished casings at the earliest possible moment.
