Mystery car with a problem

An Arrol-Johnston true to its pre-WWI advertising: all cars sold with detachable wheels... and a spare, which could all be wood, wire or steel spoked.

This car’s probably Sankey steel wheels appear to be fitted with non-original North British Rubber Company, “Clincher Cross-pattern” tyres, which first appeared as the Clincher Limousine Cross Tyre at the London Motor show in November 1913. The tyre was used by military vehicles during WWI, notably surviving up to 14,000 kilometres on Italian Red-Cross ambulances and was manufactured until November 1922.

Between November 1911 and 1914, Arrol-Johnston advertised an 11.9-h.p., with a torpedo body and detachable wheels fitted with 760x90mm grooved Dunlop tyres, for £285, whilst the 15.9-h.p., with 815x105mm Dunlop tyres on Sankey steel detachable wheels, was £400. The 11.9-h.p. was shown fitted with flanged mudguards front and rear, and a spare wheel well below the off-side door top and inset deeply into the running board, features not all apparent on a 15.9-h.p. However, a two-seater 15.9-h.p. looking much like this but on wire wheels was £370.

The side-lights have convex lenses and, if clean, act as mirrors. 5double-decker buses used to have them in the stair well so that the conductor could observe the rear platform from the upper deck.) In the case of this photograph, a careful examination of the offside side-light shows a blurred, but moderately clear, image of the photographer against a background of a chalky road. The registration is an old London one. Can your correspondent identify the address in London where the car might have been registered?

I'm plumping for a Scottish built Arrol-Johnson of around 1911/1912 period. Either an 11.9 or 15.9

An Arrol- Johnston c1912

In my belief it is an Arrol-Johnston of 1912-1914.
