Transformer, light socket, and switch. What's it for?

I know what the components are, at least I think I do - but what the heck is this thing for? And is it valuable? Came out of a barn and is 11" long. Also, the two jacks at the bottom are patch cords that can be plugged in and out. I have an idea of what it is, but want to hear what you guys think.

I think it is for checking generator armatures.

I think it is a vintage magneto of some sorts, look up images of lawn mower magnetos, and vintage magnetos.

Simple yet efffective device. Nice fast solve Indian Steve.

Yeah Indian Steve nailed it, do an image search for vintage armature tester. I only saw the magnetic pickup because I didn’t look close enough.

Indiah Steve is right!! It's called a " Growler" It's a crude way to check armatures. If the windings were good it would make a growling sound. Tony
