This insulator has no makers mark. It has an interesting Glaze color. It is 4" tall 2 3/4" diameter at the bottom. It is in good condition, I don't see any chips, cracks, hiwever these is a chip that was glazed so there during production. There are some spots that were not glazed and it has one bump that was glazed. There is some staining on the unglazed parts on the bottom. Please see photos as they are part of the description
