Eighty-five years ago, Britain was at war, but that didn’t mean that the British housewife couldn’t enjoy a little music while she worked.  If your radio was in the living room, she was spending time working in the kitchen.  The perfect solution was the addition of an extension speaker.  She could then pass the otherwise dreary hours listening to her favorite programs.  This ad for Stentorian speakers appeared in Practical Wireless, May 1941.
