All over the world there will be huge stores of war material to be disposed, and the old parable of the "ill-wind" may be repeated. Here in Australia it has been estimated that when the war finishes there will be radio components in store to the value of about ten million pounds. Amongst these parts will be lots of transmitting valves, condensers and other parts which will not be suitable for use in broadcast receivers. They will be a wonderful windfall for those who operate experimental transmitters. There will be great stocks of components suitable for use in building the thousands upon thousands of receivers which ·will be required to satisfy the overdue demands of the ordinary listeners, and the whole of the radio trade will need to handle things carefully to ensure that these parts are put to good use without upsetting factory production or affecting normal trading. Some radio traders are apprehensive about the possible effects of the release of war surplus stocks, but others are quite confident that the matter can be easily handled by the trade, in close co-operation with the technical press, bringing about a boom in technical radio, with all-round benefits to the radio trade as a whole. - A.
