Hi Harvey, George must have read the The Edison "Home" Phonograph, 1896 - 1901 in the Sept 2006 CAPS The Sound Box. This was a wonderful article well worth the price of the annual subscription. I still refer to this article for the most valuable information it provides.
I cannot say enough about how enjoyable The Sound Box is to read.
