Hancock - Head Chateauroux} Rm{William Robotham - Chief Engineer}/Std.15/JH.4.5.37. We have carried out tests on a pressed blade type of fan as per the one which you have fitted to 3-B-IV and also on a pressed blade construction designed for Wraith. As a result of these tests we think it advisable to standardise the Wraith type of blade (EW.94) on Bentley and 25/30 H.P. cars. We are therefore forwarding to you a second fan fitted up with this type of blade. Will you please fit this to 3-B-IV when it arrives and return to us the two fans which will have been removed from 3-B-IV. Rm{William Robotham - Chief Engineer}/Std. | ||
