Design in Post-war
0 UT of 238 exhibitors of components and accessories at Earls Court, nearly all are, in effect, showing something new, because not even the greatest war in history has caused stagnation in design. Improvements, no matter how small, have, in recent years, been made in almost every one of thousands of items.
Severe constraint on editorial space, however, demands that attention be devoted only to those articles of equipment upon which the brightest spotlight is being turned at Earls Court— the newest among the new. Even so, ii is difficult enough to appoint an order of rotation for the discerning spotlight.
From many points of view, and not least that of public safety, braking systems must reflect the bright beam. The two-leading-shoe type of brake has a strong following. A new one is shown by Kirkstall Forge, Ltd., Leeds, 5 (Stand 377), and is suitable for medium-weight vehicles.
