1946 Kohler cast iron!
Today, (after a 7-hour road trip) it is no longer for sale and is sitting in our garage!!!! It needs some TLC but it's actually in very good condition for a 65-year old sink. I haven't done any work on it as yet, but when I do I'll let you know how those stains clean up.
Gosh! I would never have thought when I woke up this morning I would be taking a trip to North Carolina, much less becoming the proud owner of this 150-pound nice old kitchen sink! I'm a happy lady.
Another thing to check off my list of wants :)
