Suggested method of casting/oil passage holes in Twin Valve Shock Damper. The casting is to be produced in cast iron to the rough pattern made by Rm {William Robotham - Chief Engineer} /Clm {D. D. Clapham} , and the pipes built up as shown on the above scheme. Approximately 15" of .250 i/dia, and 8" of .1875 o {Mr Oldham} /dia piping will be required in S/D.2031B quality- 18 SWG(.048) thick. The above is an effort to eliminate costly drillings which appear on the Twin Valve Shock Damper. Attached to Rm {William Robotham - Chief Engineer} /Clm {D. D. Clapham} 's and RHC {R. H. Coverley - Production Engineer} /Vs {J. Vickers} copy is a blue print of SCD.1456. (signature) Ald {F. Allwood - Experimental Design} By {R.W. Bailey - Chief Engineer} /Ald. {F.
