Ev.{Ivan Evernden - coachwork}9/JH.25.4.40. re Fan Rippletto. On PL.202 herewith we show the fan for Rippletto. The spider and pulley are those specified for B.60 except that the gauge of the spider has been reduced to 10 S.W.G. (.128) The fan blade is also that for B.60. except that 1.5" has been cut off the end of each blade. It will be a matter for experiments to determine exactly what the smallest diameter of fan we can use on this car. Ev.{Ivan Evernden - coachwork} Enclosed 4 copies of memo. 2 prints of PL.202. | ||
