The Experimental Dept. are not yet in a position to give a decision on the type of 14 m/m Sparking Plug for the Bentley Engine. They recommend we order equal quantities of K.L.G.-765A and Lodge-X.335 for the first 15 production chassis. These plugs should be obtained as soon as possible as the Test Dept. are pressing for them. Will the Experimental Dept. please make a recommendation so that the order for the remaining 185 sets may be placed. 10,000 MILES BY/SS.{S. Smith} | ||
