| From Exp. Dept. Copies for: Mr Johnson Mr Royce Mr Nadin Mr Bailey Wor{Arthur Wormald - General Works Manager}/Hy{Tom Haldenby - Plant Engineer}4/L14513 May 14th. 1913. Report on Experiment No.140 Modification of special Nuts G.2093 for Torque Tube Bolts etc. This is a small improvement by lengthening the nut slightly and by making the hexagon part longer so as to make it easier to operate by box spanner. I find it quite satisfactory. I S S Haldenby | ||
