My sister, who was born in the early 60's, had one that she let me use all the time in my bedroom as a little kid. It was battery-powered, and its footprint was about the size of a hardbound novel volume.
It had a big, white plastic tone-arm and a tiny plastic platter that was very vinyl-unfriendly. The stylus didn't track very well--it constantly skipped. And if I recall correctly it could play three speeds (33-1/3, 45 and 78 RPM.)
Because it was so small and simple, there was no cue--you had to pick up the tone-arm and set it on the record--and I don't think it even had the standard little side-piece with which a person could gingerly pick up the headshell. You had to put your hand around the entire headshell to pick it up.
There was no anti-skate, and there were no pitch controls--which are generally standard equipment on a good brand-name turntable built today.
Another note that might be important, or might not depending on what information you will be needing, is that these tiny battery-operated turntables (at least the ones I have personally dealt with) were never automatic. They were the kind you had to watch constantly to make sure they were doing their job (some of the performance of turntables can be attributed to records, but most performance issues have to do with how the turntable is built and what it is able to do.)
I hope this helps, and good luck with your manuscript.
