No I don’t really, I’ve just taken a punt on a flat rim, amber flashing, well made soda glass(fairly sure),pointy pontil(don’t really know how bohemian that is ?) and a red core for the stem ?.Is saying bohemian really going to put people off saying it’s not ?i don’t know ?,but I’m more than happy for them to do so , Have you got a feeling about it’s origin ?
