Selection of old Walkman-style personal stereo radio cassette players - don't think any of them are working so sold as spares only - the oldest one Cap-10 is very unusual and reminiscent of the original Sony Walkman so maybe best used for a prop or fancy dress? The Aiwa one has Dolby, Metal Tape Function and Auto Reverse so quite high spec but although the motors drive ok there's no sound output.

Hopefully of use to someone who is more technically minded than me!
