| X8781d4 To EY. from EFC. c. BY/RD. c. Mr. Brock. EFC5/T10.2.28. Herewith we send you revised copy of Production Specification of Inspection & Test of Ignition Distributor & Contact Breaker, this being now suitable for the recently standardised design of contact points (tungsten) with slightly flexible fixed contact point support. The mechanical test of the 20 HP. governor, called Part B in the 20 HP. case is not included in this, as it is the same as has been previously issued for the old contact breaker. EFC. | ||
