| X 60209. 21.5.30. Extract from Mr.Hancock's report on 23-EX after 9,000 miles. IGNITION WIRES TO LOP. E.77671. ALUMINIUM IGNITION TUBES E.80411/2 TO SCHEME 1203. The aluminium ignition tubes have remained in good condition. The ignition wires are quite O.K. with the exception of those supplying No.3 & 4 plugs on the exhaust side, the heat from the exhaust manifold has made these become very slightly perished. There are slight cracks in the insulation. | ||
