| To Hs.{Lord Ernest Hives - Chair} From Rm.{William Robotham - Chief Engineer} Rm.{William Robotham - Chief Engineer}5/MH.{M. Huckerby}6.2.39. We have no machine of any kind for testing the poundage of road springs accurately in the works at present. With modern low rating springs it is very important that we should be able to check the poundage to avoid costly changeovers. Experimentally, of course, a spring rate measuring machine is imperative. We should be glad to have your agreement that we may purchase an Avery No.662 Spring Testing Machine, price £228 as per the attached quotation. Rm.{William Robotham - Chief Engineer} | ||
