| SECRET. STEADMAN S/W To RHC.{R. H. Coverley - Production Engineer} from Sg.{Arthur F. Sidgreaves - MD} Copy to Cs. Dd. Rs.{Sir Henry Royce's Secretary} Wd.{Mr Wood/Mr Whitehead} Rs.{Sir Henry Royce's Secretary} Widney Concealed Bonnet Hinge. Referring to RHC{R. H. Coverley - Production Engineer}/SB.{Mr Bull/Mr Bannister}1/MJ.7.1.38 this is to confirm the decision taken yesterday to fit up Widney Concealed Hinges on the advance 6 Wraith chassis. I am not quite sure whether we decided to fit them up in the steel or the aluminium but doubtless you know. If not, perhaps the best way would be to try three of each. I should also like to hear from you about the bonnet with this type of hinge on the Jaguar which we are buying, after you have had an opportunity of examining it. Sg.{Arthur F. Sidgreaves - MD} | ||
