I can't remember where or when I purchased this book but it contains a
gigantic amount of information about automatic record changers and recorders. Lots of pictures and illustrations too. It's amazing to me that one person could assemble this much information in one book.
Please send a PM with interest. Actual USPS Media Mail shipping cost is extra. It's a pretty hefty book but should still be pretty inexpensive to ship using Media Mail.
Thanks,
Doug
