Alldays and Onions, Ltd., Matchless Works, Birmingham.

The Allon is here shown for the first time with a three-speed gear box of the firm's own manufacture, the change making the machine more suitable for sidecar work. Accordingly a complete outfit is exhibited and is a small but practical vehicle not too elaborate, yet with all the fittings that the average rider would desire. The engine is quite a normal type two-stroke also made by the firm, and transmission, is by chain and belt. Two models are offered the engine in each case having the cylinder cast integral with the top of the crank case, one having a two-speed gear box of the type used successfully during the present year.

A characteristic feature of the design is the twin tank which bridges the top tube and contains both petrol and oil, the latter in one section of the right hand tank. To connect together the two petrol reservoirs a bridge pipe of U shape is carried under the tanks.

This is one of the few machines which have a small contracting band brake on both front and rear wheels, the brake surface provided being ample in each case. As regards detail work, leg guards are standard and should be convenient; advantage being taken of the upright shields to carry the tyre pump in clips secured to one of them. Again, the new fork with its leaf spring almost entirely concealed is worth a close inspection as, externally, it is one of the neatest in the Exhibition, and certainly it is easy to clean. Lastly, there is a small but effective belt guard over a portion of the belt rim, and in just the position to catch mud which otherwise would bespatter the belt.
