| 23/1/39. Re K.L.G. FLB50X Sparking Plugs. Similar in external dimensions to standard FLB30X plug, but has a higher heat factor. Offered by the makers as a cure for the excessive electrode wear experienced on the Bentley. We find, earth electrode running too hot for Continental conditions and rather too cool for town conditions. Print A.{Mr Adams} Plug after 8,900 miles on B 35 KV, a Paris trials car. S.R. reports no improvement with regard to electrode wear. Print B. Plug after 7,070 miles in England on Mr. G.{Mr Griffiths - Chief Accountant / Mr Gnapp} H.{Arthur M. Hanbury - Head Complaints} Withey's Bentley (B190 KT). See 6001. RM{William Robotham - Chief Engineer}/RC{R. Childs} 10/JH 23-1-39. | ||
