Sidgreaves - MD} WOR.{Arthur Wormald - General Works Manager} C. to HS.{Lord Ernest Hives - Chair} DY.{F R Danby} SECRET ORIGINAL E4/M28.2.31. JAPAN 3. TWIN BATTERY IGNITION. X1109 In arranging the position of the oil pump and battery ignition drive we have had to take a forward look at the ignition wiring and conduits, and on print of LeC. 2878. herewith is shewn an external view of these together with the distributors and coils. The present standard style of H.T. moulding with vertical connections does not suit us very well and as the hand operated movement of the distributor is very small we propose to use the cap pattern in which the wires emerge from the side of the moulding.
