Water Pitcher, BIM Panel-Optic, Wheel-Ground Bands

This is 7 1/2" high, ~6" major diameter, 4 1/8" rim diameter, 4" foot diameter; weight is ~30 oz. I'll guess its capacity is ~2 quarts. There are no chips, cracks or other damage; aside from the foot wear, it appears unused.

Lots of wear on that foot. There are 16 vertical optic panels, about an' inch wide. The two ground bands are each of 6 fine lines, 3 on each side of a 1/4" wide matte stripe; they're right at 270 degrees, ending uniformly equidistant from the handle, which is affixed to one of 2 mold seams, the other seam being centered on the pour-spout.

Is the pattern familiar to any of you? I can imagine it had matching tumblers, an' may have been used for iced tea or lemonade. Can it be dated with any accuracy? It looks 1930's-40's to me, but thats conjecture. Thanks for lookin'!
