| FROM E.{Mr Elliott - Chief Engineer} Copy to BG. [crossed out] Copy to WOR.{Arthur Wormald - General Works Manager} [crossed out] Copy to HS.{Lord Ernest Hives - Chair} E1/M21.8.30. x7000. x7190. L.H. P. 2. SUMP DRAIN PLUG - LeC. 2788. re. BY1/G20.8.30. The original of LeC. 2788. shewed the sump drain plug screwed into the aluminium direct as R.{Sir Henry Royce} now desires it. The design committee in being during the early part of this year asked for and approved of a design with insert. There is another L.H. P. 2. design - LeC. 2791. Auto Klean Filter, in which an insert was used for the sludge plug in deference to the committee's views. This insert also is not locked unless you have locked it, and might well be dispensed with in a similar manner. E.{Mr Elliott - Chief Engineer} | ||
