Woodhead brought out a device known as 'Alf's Button' which was supposed to function on much the same lines as the 'Rectaskid'.

This however, has not enjoyed a large measure of popularity. (b) Auxiliary spring devices. As we have previously pointed out under the section entitled "Shock Absorbers", there are a number of auxiliary spring devices marketed to either increase or decrease the main leaf spring rating over some range of its deflection. The idea of the Nevajah is that a weak main spring can be fitted giving good riding at low speeds without the axle hitting the frame over bad roads at high speeds. [Diagram Text] NEVAJAH. contd. | ||
