The attached list outlines the development work required on Shock Absorbers. We should like arrangements to be made for development work to continue undisturbed, even when dampers have to be sent to W. Bell for loading or re-loading. The Armstrong damper up to the present has not shown any fault that will make it an impossible damper. The advantages to be gained are:- (1) Large reduction in cost. (2) Less likely to knock. (3) More convenient shape. (4) Better damping at high frequencies. There is, however, a large amount of development work to be done before the one size of damper can be made satisfactory for all cars. Rm{William Robotham - Chief Engineer}/Les.{Ivan A. Leslie} | ||
