Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell}4/MH.{M. Huckerby}7.12.38. B.60 & B.80 KLINGERIT CYLINDER HEAD. We have had a request from the makers of the above joints to increase the steam release holes from 5/32 to .250 dia. on account of the constant renewal of cutters required in the case of small holes. If there are no objections therefore, we should be pleased if you would make the holes in question .250 dia. Additional to the above the 5 extra .312 holes in B.60 gasket should be included as mentioned in the memo Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell}2/MH.{M. Huckerby}17.11.38.
