Condition: used, vintage, no chips or cracks, rough inner edge, dish center is pushed up or domed a bit
Comments: Either a poultry water dish, or an advertising item for poultry products. Circa 1918 they were the largest poultry supply house in Indiana. 1922 they made poultry feeders, later they made grass seeder products; now the company does sheet metal work, per my research.
