This next photo is truly a mystery as submitter Ray Maciejewski of Vesper, Wis., also has no idea what the device is.

Maciejewski said that he found the device in the town of Richfield over 50 years ago. For added effect, he also mentioned that it came from Richfield’s landfill, so clearly its use even 50 years ago had worn out.

So, readers, “What’s This?” and why does it work the way it does?
