This piece was manufactured by U.S. Glass Co. as part of the Dubonnet / Kings Crown pattern, catalog number 4016-40. Catalogs also provided the following description: 24" Diameter 8 1/2" High - Complete with Ballbearing Spinner.
The piece has 0 seams, 0 thumbprints, and does not have a start/ray in the center/base. The piece was hand pressed, and when done, it was painted/stained by hand.
As staining can be done at any time against the glass, variants are possible. Our standard colors reflect only those known to have been applyed by the manufacturer.
Sources tell us that this used the 23" plate and the punch bowl foot as the glass components.
