| X4308 To Hs {Lord Ernest Hives - Chair} /AJL. from EFC. {E. Fowler Clarke - Electrical Engineer} EFC {E. Fowler Clarke - Electrical Engineer} 9/T23.8.27. A.T. SPEEDOMETER. A 246/745 15/52 Herewith we hand you A.T. speedometer belonging to chassis 12-EX. This has been carefully tested at any rate for speed indications, the idea being to test it again after it has run a large mileage, to see if there is any loss of magnetism in the permanent magnet. Will you please now have this replaced on chassis 12-EX. EFC. {E. Fowler Clarke - Electrical Engineer} A 246 | ||
