We have now standardised the new K.L.G. sparking plug of the non-detachable type, insulated with the Bosch insulator which K.L.G. are now making in England under the name of 'Corundite'. This insulator has remarkable properties in that it has three times the mechanical strength of the best known 'Ceramic' insulator and has approximately ten times the heat conductivity, it is also impervious to lead attack although it is possible for a lead glaze to form on the insulator. The type numbers of the sparking plugs standardised are as follows:- P.J.Chassis. K.L.G. type FE.30.X. - this plug before standardisation was previously known in its experimental form as type E.26. Bentley and 25/30.HP. K.L.G. type FLB.30.X. - this plug before standardisation was previously known in its experimental form as type E.27. Supplies of these plugs are now available and can be obtained on request at the Stores. Rm{William Robotham - Chief Engineer}/Wst. C | ||
