As part of that "contents of T&C grinding garage for $1,000" deal, I
acquired a Jones and Lamson comparator, looking old and having some
rust on the table due to the owner not oiling it.

Would I be justified in just scrapping it for metal, (700 lbs), as it
looks like no one one needs them any more. It would seem that a couple
hours of my guy cleaning it would be a waste.

Am I missing anything?
