Head Offices, Works and Design Dept.: DALLOW ROAD, LUTON. Messrs: ROLLS-ROYCE LIMITED, DERBY. 20th, October, 1932. Dear Sirs, With reference to the Marles-Weller Steering Gear which we have despatched to you to-day, we would draw your attention that the cone splining operation on the big end of the lever is not as it should be, as we had considerable difficulty with the broach and subsequent operation due to the fact that in the design of the head of your drop arm the metal is reduced towards the outer faces, leaving insufficient support for this operation to be carried out satisfactorily. As, however, it would appear to be sufficiently good for preliminary purposes we are forwarding same with the Steering Gear, and have put in hand a new forging with larger faces so as to give the necessary support in machining. The new Drop Arm will be completed as soon as possible and forwarded to you to change over. Assuring you of our best attention at all times, We are, Yours faithfully, for ADAMANT ENGINEERING COMPANY LIMITED. S. Carlton Smith Director. | ||
