The whole 45 story is long and sort of convoluted, but it's all in a book by Phil Vourtsis, in New Jersey. He did it a few years ago, and if you go to: http://app.infopia.com/Shop/Control/fp/user/Shop/Control/Product/fp/vpid/652 767/vpcsid/0, you'll see all about it. There are pictures of the prototype changer, and the guys who designed it. I got one of the first copies. My clear case player attachment is illustrated in it. > [Original Message] > From: Robert Wright <esroberto at hotmail.com> > To: Antique Phonograph List <phono-l at oldcrank.org> > Date: 12/27/2006 4:44:50 AM > Subject: Re: [Phono-L] 45rpm players from the late 30's?? > > > ----- Original Message ----- > From: "Douglas Houston" <cdh041 at earthlink.net> > "RCA actually startede the 45 > system in 1939, and had it pretty well ready for production during the war, > but couldn't do anything with it then." > > Is there any readily available material I can study on this subject?
