| SECRET. 628 Copy to Der. Im. HPC. E {Mr Elliott - Chief Engineer} /HDY. {William Hardy} 4/M.10.6.37. WRAITH III. GEARBOX. We send herewith N.Sch.5168 showing a modification to the speedometer drive made at the request of the Experimental Department. A blind ended bush G.81912, as used on the Phantom III, is to be used at the back end of the spindle which drives the speedometer cable, as the riveting in of the disc to close the present open ended bearing is objected to.
