I found a gazillion 'South bend commercial range' on line.

Here is a link that might be useful: Southbend commercial range

Thanks for the link, hendricus. I have mostly found new ranges which are around $4000 with the specs mine has, and now notice that the hood is priced differently from the motor in most cases... this is going to be quite the drawn-out process, I think!

The hood does have all of the modern code requirements of fire suppression, etc, right? If not, you may not able to get much money at all for it. For 25 years old, you'll be lucky to get $800 for the pair even if they are lightly used. Put them on Craigslist in the Business category and see if you get a bite from a new restaurant. Be prepared to go lower if you don't get any calls the first week. And make sure you state in bold letters to have plenty of help to move it! In fact, due to liability issues, you might see if you can rent an air sled and move it from the house to the garage so that no stranger bangs up your home.
