| 26027 E.{Mr Elliott - Chief Engineer} From Hs{Lord Ernest Hives - Chair}/Wst. c. to By/RD. c. to Sft.{Mr Swift} Hs{Lord Ernest Hives - Chair}/Wst.3/MA.8.11.33. STAMPED SLOTTED ARMATURE PLATES FOR STARTER MOTORS. The use of these plates on our starter motor should give us a higher efficiency when rolling the engine, as well as effecting a reduction in production costs. Will you please arrange for a Bensport and Phantom II starter motor armature to be instructed for our test, made up of Sankey's "Lohys" stamped slotted plates. In the case of the P.II armature we might delay ordering any plates until we have established whether the 33 slot armature, now being instructed, is any better than the standard 37 slot.
