Awesome chotchki!
When you said early 70's my first reaction was "No way, Walkman of any type didn't exist until the 80's!"
Crazy that this existed and yet it took so long for a walkman to come out.
Whether it's spare parts, a weird AC adapter, a cool sweater, an obscure movie, a tool... show it off here!

It was probably a dictation machine similar to

I'm not sure why it took a decade for the brain wave of the Walkman to happen, perhaps pre-recorded tapes were still very expensive and/or sounded like anus before better formulations, noise reduction, and things like HX Pro. It also appears making quality heads for compact cassette took a while.
Tape was super expensive compared to vinyl for tape that sounded as good and while there were portable vinyl and reel-to-reel machines nobody was carrying one around with it on. At the time of the TC-50 the general consensus was that you couldn’t make a cassette that sounded as good as a reel-to-reel or vinyl because it would be too big. There were compromise formats like Elcaset and 8-Track, but they had their own fallings and were both quite large compared to compact cassette. It wasn’t until the middle of the 70s that the price and the quality of 1/4 in tape hit a place where it was able to start supplanting vinyl and larger reel-to-reel formats.
Cassette is 1/8 of an inch, reel to reel is 1/4 inch.
8-tracks are 1/4 in, reel-to-reel existed in several sizes.
