I remember, but never actually saw one. Wonder how they did, while driving? The roads were in better shape back then, so it may not have been as bad as some might be thinking.........
I had a similar record player back in the mid 60s. I used to play records on the school bus, on the way to school. The bus driver even liked it, because all the kids were quiet, so they could hear it...........
Had forgot about that little record player, until I saw this.
