This piece was manufactured by Unknown Manufacturer as part of the Kings Crown (Variant) pattern.
The general dimensions of the piece are: Height: 3 5/8"Diameter: 2 1/8"Depth: ~2"
The piece has 4 seams, 8 thumbprints, and does not have a start/ray in the center/base. The piece was machine pressed, and when done, it was painted/stained by machine.
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.
Assumption based on depth of the thumbprints and overall quality makes us believe this was machine pressed, but that is only a guess.
