I have a crock that is salt glazed with what looks like the number 4 on it. It would hold about 4 gallons (almost 12” tall). I think it might be Red Wing, but not sure.
Cassie, well the handle does look to be Red Wing. The cut line is not normally seen on Red Wing pieces, but this could have been a potter from another pottery that came to Red Wing. With all this being said, I am going to change my mind on your piece and go with Red Wing. Value $175 to $200. Al Kohlman
