You're on a roll!
Picked up the sink today in Asheville nc. In as good or better shape than the owner described! Was made 9/22/38! He took it out of a house they were restoring as owners wanted more modern sink in utility. How dumb. Heavy AF
It looked great in the image you posted, I was surprised when you said there were two chips, I didn't see them.
If you end up not having a place for the second sink with your build you can get it prepped for installation and sell it.
Leave the sink as-is, the patina in priceless combined with a little provenance in today's market.
Just get the drain ready for install and put a nifty mixer on it and you could probably get better than a grand for it, $1500 even.
Highend interior decorators are starved for such items.
People are lost on proper restoration, gotta be willing to chase down original parts and pieces.
Keep the level of a trap in mind with the one you're installing.
It's going to be exceptional low, the receiving drain connection will have to be a perfect match.
Notta issue if you're thinking ahead with your construction.
