Glassies, any idea about the maker and pattern?

At first I thought of Fostoria Baroque, but alas, I think not.

It's poured into a mold, I think. Base has a concave oval in the center/bottom. Bubbles can be seen and it weighs a TON.

Any direction I should head in for more information? TIA!

 

This is glass and not lead crystal, correct?
Lead crystal would indicate European origin and maybe not so old.

When I see glass this heavy, I think of companies like New Martinsville, Heisey, Duncan Miller, Tiffin.

 

That's helpful I'll start some searching tomorrow Thanks!

 

This was pressed in a mold. This is not a typical US shape which has me thinking post WW@ Europe

 

Yes, that is why I asked if it was lead crystal. I'm not sure a European company would have done it in glass. Would they?
