W. E. Brough and Co., Basford, Nottingham.
The centre of attraction on the Brough stand is the 496 c.c. flat twin sports model, which is guaranteed to attain a speed of 70 m.p.h., or, if a sightly increased price be paid for extra attention, 80 m.p.h. The model in question is one of the best-looking machines in the Show, having a nickel-plated tank with rounded corners, and, of course, the long separate exhaust pipes ending in an aluminium fish tail, which all good sporting models should have. This year the cylinder head has been considerably modified, substantial roller bearings are used for the connecting rods, and the aluminium pistons are of the firm's own alloy. The location of the handle-bars, foot-rests, and saddle affords an exceptionally fine riding position with a real sense of control.
692 c.c. MODEL.
70x90 mm. (692 c.c); twin cyl. four-stroke; side-valves; drip lubrication; Amac carb.; gear-driven mag.; 3-5p gear; clutch and kick-starter; chain drive; 26x3in. tyres. Price; Solo, £90; with Sidecar, £120.
The other two models on the stand are the new 496 c.c. machine which has side valves and 26x3 in. tyres, but otherwise is much on the lines of the sporting model, and the 692 c.c. model especially meant for sidecar work. Both these machines have the chain drive from engine to gear box. concealed and protected by an aluminium coverplate, in distinction to the sporting model, on which the chains are visible. These two models are fitted with very large mudguards, affording ample protection to the rider and to the mechanism.
The location of the gear box (under the rear cylinder) and the method of engine mounting, permits the wheelbase of the Brough to be kept within reasonable limits.
