Is there any readily available material I can study on this subject? The development of technology is one of the most importants parts of this hobby for me (particularly failed formats), and this pre-war 45rpm thing is coming as a total surprise to me. I knew Bell Labs (or was it Western Electric) had developed the 45/45 stereo groove in 1929 and then sat on it for 30 years, but this other is news to me. By the way, if it came up in this conversation because we're dicussing what threads should and shouldn't be welcomed here, I'd like to postulate that if anyone actually has one of these pre-1949 45rpm machines, we'd all damn sure like to hear about it! thanks, Robert
