Argyll Flying Fifteen

Built in 1910 by the Argyll Ltd (formerly Argyll Motors Ltd and originally The Hozier Engineering Company), a Scottish car manufacturer based in Dunbartonshire. Vehicle production ceased in 1928 but the company lasted another four years until 1932.
This example is on display in the Royal Museum Of Scotland, Edinburgh, where Lego-Sprog loves running up the escalators and then trying to run down them. Fortunately we kept him on his harness so he had to make do with 'running' down the stairs while I did my back in holding him under his arms!
I tried to find some actual technical specifications for the car but found none save that this model was sometimes bought for use as a taxi.
