Bit late on this one but can advise that the car registration U-1468 was issued by the County Borough Council of Leeds in the latter part of 1910. The car shown was manufactured by one of the earliest and most prestigious manufacturers of the day, Napier, who made their first car in 1899. Their vehicles were mostly very large and exotic, racers and record breakers. At the other end of their production programme, they also manufactured a vehicle that became very popular as a Taxi in London and elsewhere. From 1908 to 1911 they made over 700 15HP Landaulettes available with either 1.3L 2 Cylinder or 2.7L 4 Cylinder engine. Many were exported. During World War One they supplied over 2,000 trucks and ambulances to the war effort. So this is a cca 1910 Napier 15HP Landaulette.
