Sony BM-575 Portable Microcassette Dictating Machine

here's a vintage Sony cassette dictation machine model dictator BM 20 this thing is a tank it wears a ton and probably got a lot of metal inside it cuz it's probably around 12 13 pounds maybe and looks like it's probably from the sixties maybe the 70s I'm not real sure works everything works on it except for the reverse functions I'm guessing it has a broken belt I just wanted to do a quick demo of this before I put it up on eBay and get rid of it because I've never gotten this out and tested it before yes he won't run in Reverse you can hear the motor running but the tape doesn't move I'm hoping somebody could give us a good home and restore it because it's actually cosmetically it's in really good condition and like I said it seems to be very well built probably all original and hopefully with just another new belt or a roller or whatever's going on in there it'll probably work a hund
