This page does a really good job of differentiating between the different models of phonographs made and who was making them over the years. The site focuses on the Victor-Victrola “Talking Machine”, but it does mention the RCA incarnations and several others. The site was meant more for collectors and people who want to see how much their old phonograph was worth, but it has a good historical aspect as well. The person who compiled all the information is quite knowledgeable about these machines and appraises them as a hobby, and part time job.
