Wollensak 3m 2550 cassette player recorder. Looks to be vintage and possibly collectible.
UPDATE: I powered this on and some basic features were tested. I can tell you that it records, plays, rewings, fast forwards, ejects the tape and you can adjust the volume. I found that if you want to record you need to hold down the record button and then press the play button. Although this works, the power light does not light up when this is turned on. I did not test any further. You only get what you see in the photographs (machine, case cord and 3m microphone). Sold as is.
Please e-mail with questions or for additional photographs. Thanks
