| TO HS.{Lord Ernest Hives - Chair} FROM DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork} C. to LHS{Lord Herbert Scott}, RY, SS.{S. Smith} ORIGINAL DA{Bernard Day - Chassis Design}/EV{Ivan Evernden - coachwork}3/M3.9.26. 4th/9/26 20HP. STEERING COLUMN STAY. X5430 We thank you for your HS{Lord Ernest Hives - Chair}4/LG30826. The sole influence that has caused us to design a triangulated stay for the raked column on the India chassis was the fact that the original scheme of supporting the column on the instrument board bracket and the scuttle is never used by any of our leading coachbuilders in London, nor has it been used for now close on two years. The column is always left free of the scuttle, and suspends from the instrument board bracket alone, consequently while it is reasonably rigid vertically, it is very free to move horizontally. The proposed stays designed recently would make the column infinitely more stiff than one treated by the coachbuilders present method. We have no doubt in our own minds that Sales will be satisfied with the results achieved, for it should be remembered that the rigidity of the new scheme will not be criticised in comparison with the original scheme, whereby the instrument board bracket and instrument board, together with the column, are all fastened to the scuttle rail, but it will be judged in comparison with the present coachbuilding methods where the scuttle plays no part in the support. We presume that you would be fitting up a 20HP. car with a view to testing it for yourself, and enable us to try it before submitting the scheme to Sales, and we suggest that this would be advisable before we offer a set of them for trial. In the meantime however we will ask Sales to tell us whether they have a 20HP. car with a raked column on which they would like to have this stay fitted.
