Harold Whyman - Experimental Manager} Rm{William Robotham - Chief Engineer}/Std.4/MH.{M. Huckerby}21.1.38. THERMOMETER BULB POSITION ON WRAITH. We wish to run all our up-to-date cars with the thermometer bulb situated at the front of the head. Existing heads can be modified for this purpose to SCD.177. 26.G.VI and 27.G.VI have already been modified in this way. Will you please modify 28.G.VI and 29.G.VI in this manner as soon as opportunity presents itself. The existing thermometer is used unaltered. We are also handing to the Exp. Shop one Wraith thermometer and oil gauge unit. Will you please fit this to 29.G.VI in order to avoid booking out a new instrument from production. Rm{William Robotham - Chief Engineer}/Std. | ||
