It's fun to go to a garage sale or estate sale and buy a box of junk, just to see what's inside. Most often all I've done is purchased someone's trash and paid them so I could throw it out. You might wonder what sense there is in that, until you find something you've never seen before.
Can you guess this gadget from the first look? I know someone can. Still stumped? Let's try another view.
Certainly there are gears and an axle, but what's it turning?
Here's the reverse. Some copper pieces and what could be a single magnet arched over the top. More pictures? Sure.
The coloring is a little different due to my experiments using a flash. I didn't show a picture of the wire wrapped armature that spins around the axle. So, it looks like it was meant to create a charge, but for what device exactly, and what year? If you have questions or guesses, please leave them i the comments. I gotta know.
