Antique Minnesota Stoneware Co. Redwing Early Salt Glaze 2 Gallon Double P Crock
It does appear to have either one hairline, or a repaired crack. As you can probably see in the picture the area around it is a little darker than the rest of the crock. Aside from that it shows normal wear. Has a couple nips in it as pictured as well.
