Rolls Royce, Ltd. DERBY. For the attention of Mr. Leslie. Experimental Dept. Dear Sirs, With further reference to our telephone conversation of this afternoon, we enclose herewith a drawing of arrangement for adjustable leak. Enclosed also is arrangement drawing of the valve gear of the shock absorber in your possession. You will notice that there is a 3/16" diameter pin on the end of the cam spindle, this has been added to obviate the necessity of end location at the ball end of the lever and eases the assembly quite a lot. Under the circumstances, it does not seem as if we shall be able to eliminate the bosses down the side. Yours faithfully, p.p. ARMSTRONG'S PATENTS CO. LTD. Gordon Armstrong | ||
