I work for the Recorded Sound Archives at Florida Atlantic University. ( rsa.fau.edu). I give tours to guests, students and faculty, and I've been asked a couple times, the same questions as in my email. We have a 1907 Victor Victrola, and 1926 Credenza with electric motor and a1910 Edison cylinder player. Sometimes a get a really interested person in a tour, and I'd like to be able to answer more questions than I already can. I will go to the website you recommended and hunt for the book you recommended. Thanks again! PEACE!... and wisdom. ( I guess if there was wisdom, we'd have peace.)
