| To RHC.{R. H. Coverley - Production Engineer} from Rm{William Robotham - Chief Engineer}/NRC.{N. R. Chandler} x 512. Rm{William Robotham - Chief Engineer}/NRC.{N. R. Chandler}3/MH.{M. Huckerby}8.12.37. RE THERMOID ON 25/30 CLUTCH. The standardisation sheet has now been agreed to and we would suggest that you send away at once about 70 11" driven plates for conversion to Thermoid as this will leave a reasonable margin of the old plates in stock, even if Borg & Beck take a week before they start sending supplies.
