Hs{Lord Ernest Hives - Chair}/Std.2/KW. 27.3.34.

Will you please have a pair of hardened
P.II Automatic Tappet Rocker Shafts made in S/ZN
case hardened, otherwise to DRWG. E.84407.

These are required to be tried with the
eccentrics which you are at present remetalling
and should therefore be ground to give the same
diametral clearance (.001") as the present shafts.
