| RR 785 REVISED (10H) (D.C. 777-29-2-28) MC C.LTD COMPLETED 11.10.28 STANDARDISATION of CHASSIS PARTS. Date 23.3.28 Description of Parts. SEMI ISOLATION OF SCUTTLE SCHEME. Origin. To prevent scuttle jellying and reduce column vibration. Box: X No. 4613 No. 7430 Drawing No. Part List Experimental Test Report. We are repeatedly getting complaints of jellying scuttles and wobbling 'D' steering columns. Semi isolation cures both troubles simultaneously. In our experience it actually preserves rather than damages the scuttle. Road Test Report. Run 10,000 miles on 10-G3. " 4,000 miles on 15-EX. In neither case did the bodies suffer, in fact on 10-G3 it was the only thing that held the car together. In our experience it does not make body booming any worse. Options: A Scrap and replace at all costs, including Chassis already delivered to Customers. B Scrap and replace on Chassis in Works. C Scrap present stock and replace on all Chassis not yet handed to test. D Use existing stock Alteration effective on future Chassis.

RG.{Mr Rowledge} DA.{Bernard Day - Chassis Design} | 4.4.28 | Agreed as a temporary expedient for use with std. body mounting until the steering column support is perfected. But for sub-frame mounting it does not seem logical. DA.{Bernard Day - Chassis Design} BY.{R.W. Bailey - Chief Engineer} | 12.6.28 | Agreed. BY.{R.W. Bailey - Chief Engineer} EP.{G.
