With reference to ROY{Sir Henry Royce}/Wall/P.27.1.37, we shall have to use Antimony Lead weights until such times as the Experimental Department are in a position to standardise the rubber blocks. We do not, of course, intend to instruct the special studs and nuts until the Standardisation Sheets are completed. BY/Cgh.{W Clough} | ||
