The Pemberton-Billing sports-car mentioned in your review of Kingsford’s book on F. W. Lanchester was probably the Prince Henry Austro-Daimler with special 2-seater body belonging to him which I remember seeing at Beardmore’s Service Dept. near Euston Road when I took mine there about 1920.
And surely the worst snag in the sleeve-valve engine as used by Daimler was not smoking but the breaking of sleeves due to over-revving a cold engine?
