Looks like a typical 5 tube TRF, possibly a home brew as Terry mentioned. Check the audios and RF like suggested. It probably uses 01A tubes, so at least check the filaments for continuity if you don't have a tube tester.

These are pretty simple sets and most are pretty standard, but watch this video to get a better understanding of these sets:

I will say the most rewarding experience I've had as a collector was years ago when I restored an old set like this and picked up some stations through the little horn speaker I had hooked up.

You might have to sketch out a schematic by following the wiring and components. If you look through Riders vol 1 you'll find a lot of similar schematics. That set looks a bit beat so it might not be the best three dial five tube battery set to cut your teeth on.
