Last year the 3½ h.p. N.U.T. was introduced as a model designed expressly for solo work. However, in practice it was found that the average owner did not honour this stipulation, and thus the makers were faced with the common problem of either spoiling their machine for the genuine soloist by adapting it for sidecar work, or of providing a new model more on dual-purpose lines. Wisely, we think, they chose the latter course, and the new 5-6 h.p. N.U.T. is the result. With the exception of an increase in cylinder dimensions, it is similar in appearance to the standard 3½ h.p. model, which is also shown. Equipment includes a Lucas Magdyno lighting set. Although the 3½ h.p. machine is retained (with lower gear ratios) as the purely sold mount, the larger twin, by reason of its light weight and final belt drive, is eminently suited for that purpose as well.
3½ h.p.; 64.5x76 mm. (500 c.c); V twin four-stroke; two inlet and one exhaust overhead valves; drip feed lubrication; special Amac carburetter; T.B. chain-driven magneto; three-speed Sturmey-Archer gear; chain and belt drive; 26x2½ in. tyres.
Throughout the Show there is evidence of a widespread desire to cater for the sporting rider, and the new overhead-valved N.U.T. is a striking example. Possessing one inlet and two exhaust valves per cylinder, the engine is of a special racing type, has aluminium pistons, and gives, it is claimed, 15 b.h.p. at 4,000 r.p.m. Roller bearings are used for the connecting rods, and very neat detachable cylinder heads carry the overhead valve gear. The lowest ratio provided by the three-speed Sturmey-Archer gear box is 8 to 1. Spring forks, mudguarding, and silencing arrangements (according to the makers, "within the law but giving that deep note") are on genuine T.T. lines; but the types are amply large for comfort, and the equipment is unusually complete.
