This is a EAPG punch bowl pedestal stand/base only with a "Swirling Star" pattern and saw tooth bottom. Excellent condition with no defects. Please note: The only maker I know that uses this pattern is Imperial Glass but I've not been able to find this particular pedestal stand on the internet. The swirling star is different than the pinwheel pattern that you see with maker L.E. Smith. Therefore I will do my best to describe the dimensions:
Height: 5-1/4" high to the very top lip.
The outside diameter of the 1st lip is 4-1/8".
The outside diameter of the 2nd lip is 3-3/8" and the inside is 3-2/8".
There is a gradual 1-1/4" inside taper to the bottom which is where the punch bowl base would sit (see pics).
If you have any other questions, please ask before you buy as I cannot refund shipping if the item does not work with your existing punch bowl (you will have to pay for return shipping).
