| X1166 To By.{R.W. Bailey - Chief Engineer} c. to E.{Mr Elliott - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Bwg.{J. C. Bowring}8/KW.1.4.36. Lifting Ring (Jack Trap Door). With reference to the above F.88634. There are two modifications which are necessary to this - (1) The finger ring is too small and would be difficult to open for anyone with plump fingers. (2) The ring definitely requires to be spring loaded. We suggest that instead of carrying out these modifications it would be easier to fit the standard floor board ring F.80930, on which the two points above are catered for.
