| X.1023 To RHC.{R. H. Coverley - Production Engineer} Hs{Lord Ernest Hives - Chair}/FJH.{Fred J. Hardy - Chief Dev. Engineer} &/JH. 21. 8. 36. Bentley Bumper Bars. We are having considerable trouble on production and on 6-B-IV, due to the lead weights of the Bentley bumper bar deforming and becoming slack. As a simple means of overcoming this we wish to try weights in a harder alloy. H1. recommends an alloy of 92% lead and 8% antimony. Will you please make us one set of weights to FB.1837 in this material and send them out to Hs{Lord Ernest Hives - Chair}/GWH.{George W. Hancock - Head Chateauroux} as soon as possible for use on 6-B-IV. At the same time will you please send out the special studs and nuts to FB.2583/4/5 instructed in BY/HEB.{H. Biraben}4/M.{Mr Moon / Mr Moore} 23.6.36. Hs{Lord Ernest Hives - Chair}/F.J.Hardy. | ||
