| Rm{William Robotham - Chief Engineer} file 1023 To Hs.{Lord Ernest Hives - Chair} from Rm{William Robotham - Chief Engineer}/FJH{Fred J. Hardy - Chief Dev. Engineer} Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev. Engineer}16/AP.9.12.36. BENTLEY BUMPER BAR We recently sent through a standardisation sheet for bumper bar weights in 92% lead, 8% antimony, after having ascertained from Hl. that this material would not cost appreciably more than pure lead. Messrs Wilmot Breedon have quoted 2/6d. per bumper bar increase due to the antimonial weights. We have calculated from the current prices of lead and antimony that the price increase should be 2 1/2d. per bumper bar. We consider that this matter should be taken up with Messrs Wilmot Breedon.
