DUZMO.

When the Duzmo was introduced to the public there were comparatively few sports models on the market, and it occupied quite an important niche in the motor cycle world. To-day it is uncommon to find any make of motor cycle that is not available in some kind of sporting form, but this does not lessen the appeal of a machine the primary aim of which is to attract the youthful enthusiast.

A 495 c.c. o.h.v. engine and a close ratio Sturmey gear box are the most important items of the standard specification; reversing usual practice, a wide ratio box is supplied optionally for passenger work. Clearance tor the overhead valve gear is helped by the inclined setting of the engine, one of the distinctive features of the design.

RAY.

Nottingham is rapidly becoming an important centre in the motor cycle industry, and one of the comparatively few absolutely new makes at the Show hails from that city. Manufactured by the firm of W. H. Raven and Co., Ltd., the machine referred to is a well-designed miniature with a 198 c.c. four-stroke engine and two-speed gear box and clutch in one unit. Final transmission is by chain, and generally the detail work is carried out in exemplary fashion for so small a machine. A flywheel magneto is used, and no difficulty is experienced with the superfluous spark on the exhaust stroke.

WEATHERELL.

Consistently good performances on Brooklands track have done much to bring Weatherell motor cycles before the public eye. Perhaps this make's biggest success was to win the 100 miles Giant Handicap this year, but it has given a good account of itself at every meeting during 1922.

Three main models will constitute the 1923 range, all being fitted with Blackburne engines (250 c.c, 350 c.c, and 696 c.c.). Side valve or o.h.v. editions of each will be available.

Perhaps the most interesting machine is the smallest, which has a fully triangulated frame, of neat design.
