This is a vintage Tabletops Unlimited 3 qt covered casserole dish in porcelain enamel over steel. It has heavy brass handles and a brass knob on the lid. The pattern is of various fruits: pears, grapes, blueberries, and oranges. Tabletops Unlimited has a multitude of fruit themed patterns, and I have not been able to identify exactly which one is on this pot. However, the shape, size, and handles are identical to other Tabletops Unlimited patterns. There is a foil label on the base that reads Made in Thailand. The pot is 10 3/8" wide across the rim and about 4" deep. The domed lid adds a little more height. There is some minor wear to the enamel on the underside of the rim.
