I got this Comoy’s Grand Slam on the estate market a few months ago at a good price (also in my avatar). Liked it at once, but once the wax polish disappeared, three spots began to stand out on the side of the bowl. They sit in a funny triangular pattern and are slightly more matte and black than the bird’s eyes.Does anybody have a good eye for early signs of burnout? I’d really hate it if it were the case. I’d love an opinion.
