Thor valve grinding machine

It's certainly an antique, but I really don't know anything about it. It's been stored in my basement for at least the last 40+ years. It was left behind by the previous owner of the house. I blew the dust off of it, put a little oil in the oil cups, plugged it in and turned it on. It spins up just fine, with no strange sounds and such. The grinding wheels look fairly worn, the cords are old looking with cracked rubber, has surface rust, etc.

I'm guessing this puppy weighs in at near 200 pounds. It was made by a company that made high quality tools and other items, even motorcycles and washing machines in the beginning! This is a high quality precision tool that could be put back into service, in my opinion.

This is a Thor, model 100. Below is a picture I took yesterday. I have no idea what to sell this for, but FABO requires me to put a price in the ad, so, $150.00 buyer pays the freight from 97141. I will put it on a pallet, and I have a loading dock with forklift, so shipping is no problem.

OR trade up towards steel wheels, SBP, 7x15 OR?
