Can anyone help me with this please, i think this a piece of 1910 ish Bohemian glass, i thought it would be easy to identify.
There is wear to the base and a polished pontil, also wear to the interior base from use, it looks to have a thin coat of iridescent silver that has worn off the base rim.
It's 5 inches in height and 4 3/4 inches across the rim.
