‘Motor Cycling’ magazine announced on 19th March 1912 ‘the present demand for passenger machines has encouraged that well-known member of the motorcycle trade, Mr W. Williamson, to place on the market under his own name an 8hp two-speed side-car combination. Two models are made, one being fitted with an 8hp water-cooled engine and the other with an air-cooled motor.’ ‘Motor Cycling’ reported that the new machines were powered by horizontally-opposed twin-cylinder Douglas engines with heavy external flywheel. Cylinder dimensions were quoted as 85mm x 85mm bore and stroke and interestingly the air-cooled and water-cooled cylinders were interchangeable. It is believed that the air-cooled machines were used primarily for racing. The engine and gearbox were mounted in a duplex frame with a facility to slide the gearbox along the double tubes to take up slack in the chain. A two-speed gearbox was employed, gear change being effected by means of dog-clutches and a lever on the top tube. The frame was Coventry built and ‘Motor Cycling’ noted particularly the ‘luxurious aluminium-covered footboards’. W.W. Douglas was to ride a Williamson machine with some success in hill climb and endurance tests.

This air-cooled Williamson bears a Manchester registration number and comes with an old style buff log book dating from 1925. It was owned that year by Matthew Laurie of Staveley in Westmorland and it appears that it was acquired for The Potter Collection in 1956. Then, as now, it was in remarkably original condition although the wicker sidecar had deteriorated. The Cumberland & Westmorland Workshops for the Blind in Carlisle were commissioned to replicate the original sidecar and the bill for £4/10s for that work comes with the bike. The machine is presented in that delightful condition which no restorer can replicate and is equipped with a Brooks saddle, bulb horn, Bosch magneto and Binks carburettor. The starting handle is mounted on the offside of the frame.

This exceptionally rare machine, wearing a tax disc from 1960, comes with the aforementioned buff logbook, copies of period magazine articles and a Swansea V5C registration document. It should be noted that the frame number and engine number in the V5C document do not correspond with the numbers on the machine. Following a period of showroom display this exceptionally rare machine will we feel respond well to careful recommissioning.
