Hello and welcome!

Not my area, but we do have folk who do know about this sort of thing. Not everybody comes here every day, it might take a little time for the right person to see them, but we don't give up here.
Thanks for posting your images directly to the board and for making them enlargable - much appreciated!
However, we can tell an awful lot about glass from looking at bottoms.
Do your glasses have folded feet, do they have polished pontil scars, or simply broken ones or no scar at all? Is the rim polished or heat finished, has it been hand done or machine done?
Would you be kind enough to post more images of the base, showing any detail there might be?
And perhaps one showing the rim?
thanks!
