The inside base is super clean and very usable but could use a really good scrape and sand on the inner rim and outside to fully restore it. I tested it just on the lip as shown and it scraped off with just a spoon so wouldn’t take too long. I’ve done it too many times before to do it myself. Little bit of movement in the handle joint but will last another 50+ years of use I am sure. Very good condition for the age and still perfectly usable.
