Editorial

In this issue will be found the full details of the parts priority plan for radio servicemen. It is bound to be of vital interest to all our readers. Not actually covered in our issue, but already well publicised in the daily press, is the order controlling the sale of radio receivers. At the moment of writing, Dame Rumour has it that parts are to be frozen, too, and only released to servicemen. This is logical, so we won't be at all surprised if it has become a fact by the time these lines appear in print. There appear to be two trains of thought on the above moves. One is that control is inevitable; the other, a pious hope that the efficiency factor of the administration will be such that a better result will be achieved than could be obtained if the manpower hours of the organisation involved were applied to the production of materials and components. When the history of this period is being written, there is a chance that it will not appear as efficient as desirable, especially if account can be taken of the manpower hours wasted in wangling, hunting for black markets, waiting in queues, and so on. However, be that as it may, it is the clear duty of everyone to do their utmost to accept regulations as they come, abide by them as far as practical, and do everything possible to discourage the corruption of morals and principles which seem to be the unfortunate wake of Regulations. - A. G. HULL.
