Hs{Lord Ernest Hives - Chair}/Wst.4/MJ.9.8.33.

20/25 SHUNT DYNAMO to R.R.SCH.344.

In order to improve the performance of the
above machine we want to try :-

(a) 16 SWG. (Superfine) D.C.C. wire for the armature conductors.

(b) Stamped slotted "Stalloy" armature plates from Messrs. Sankey's.

Will you please order enough plates for three armatures with the slots suitably designed for 16 SWG. wire and to alloy for the effect of the skewing. It is proposed to grind these armatures to the correct diameter.

As we are developing this machine initially for J.3 we should be glad if you will treat this matter as particularly urgent.
