| 337 T262 Rm {William Robotham - Chief Engineer} /WB. {Mr Brazier / Mr Bell} from Rm {William Robotham - Chief Engineer} /Gry. {Shadwell Grylls} Rm {William Robotham - Chief Engineer} /Gryl/R.16.11.36. We want to obtain some more information on the co-efficient of friction in propeller shaft sliding joints. The last figures you took show that for some reason the Hardy Spicer Shafts are better than our own. Will you please carry out a confirmatory test on the P.II shaft supplied by Hardy Spicer which can be obtained from T. Fisher. Rm {William Robotham - Chief Engineer} /Gry. {Shadwell Grylls} | ||
