Vintage small stoneware mustard crock unmarked 4 5/8" tall

Stoneware crock with no maker's mark. These are often French mustard crocks but I can't say for sure--this one definitely looks vintage. Measures 4 5/8" tall and 3 7/8" across the base--a good size to keep on a desk or use as a small vase. It shows marks and wear but no chips or cracks. Smoke- and pet-free home.
