A few years ago I got rid of 3 reel to reel players. one was state of the art, digital. I had about 350 reels, conventions going back to the late 1920s. one of them had Russell's voice on it. I didn't have time to transfer them, it would have taken me years. I gave everything away.
I sold all the photo drama and Rutherford records on eBay though. Still have every watchtower magazine from 1882 to 2010, selling them off year by year.
