Now You're Hooked Shane!!
Nice score!! This percolator doesn't even looked like it's been used!! I have an AP76 myself, and it makes terrific perked coffee!! I just used it the other day (kind of my daily driver). The little water indicator on the pot (by the handle) is kewl! It lets you see how much you've put in. It's also marked inside the pot to a whopping 12 cups!!
Mine doesn't have all of the great literature yours will come with, but I do have the little hang tag. Inside, on the bottom left hand side it is dated 1966.
You are going to love it!!
