at 1100rpm. There was also a three-cylinder version of the dogcart; this was an uncouth 16 hp with the centre cylinder being of greater bore than the outer two. A 1905 Dogcart with solid wooden disc wheels still survives in Khartoum, inside the Sudan national museum, where it was supplied as a searchlight tender for the Sirdar of Egypt. Also announced at the 1905 Olympia show was the new 24/30 hp vertical four of 4654cc; followed in 1907 by the 38/45 hp of 8832 cc. In 1907 Arrol-Johnston were engaged to produce a car for the British South Polar Expedition, and it did make it to Antarctica, though it was of limited use except on hard ice, so it was restricted to the base camp areas. The car was an alcohol-fuelled air-cooled version of the 12-15hp model. The 12/15 hp twin survived in production until 1909. This was the year that T. C. Pullinger (formerly of Darracq, Sunbeam and Humber) joined Arrol-Johnston; he swept out the old range in favour of the new 15·9 hp of 2835cc. That model featured a dashboard radiator and four-wheel brakes (the latter were dropped in 1911). For 1912 a 1794 cc 11·9 hp, a 3640 cc 20·9 hp and a 3618 cc 23·8 hp were introduced. In 1913 Arrol Johnston bought land at Heathhall, just outside Dumfries, and commissioned an American firm to build a factory. This is said to be the first factory in Britain to use ferro-concrete (concrete reinforced with metal bars), and was designed by Albert Kahn, architect of the Ford factory at Highland Park, Michigan, where the Model T was produced. A-J contracted to build 50 electric cars for Anderson Electric, maker of the Detroit Electric, at the new plant but it is not certain how many were actually made. Several models of car including the six-cylinder 23/9 were built up to the outbreak of war. The first post war Arrol-Johnston was the Victory model in 1919 designed by G. W. A. Brown which had an ohc 2651 cc 4-cylinder engine of 40 hp. They introduced the model to agents in March 1919 but the first production car was not delivered until August; it was sold to the Prince of Wales. The Victory sadly proved "unsellable and unreliable", and broke down while on a Royal tour of the West of England, so that the publicity attending its debut was not
