vintage milk glass bowl w/ atterbury lace edge, base for hen on nest or covered dish

Unmarked old milk glass dish, Westmoreland atterbury pattern? This is 7 1/2" x 6" across the rim, 3 1/2" tall. It's in excellent condition without damage. It's the base to a covered dish or figural piece, but it's a pretty thing on it's own, too!
