Many thanks Della..
SNAP...nice are'nt they!
quote from IVO..."The yellow ("citrine") ashtray would most likely be Zbs, Zeleznobrodske Sklo and from fairly recent vintage."
Is that a confirmed ID?? Personally I would'nt have guessed a recent vintage..mine had a lot of deeply ingrained grime that was'nt easy to shift at all (you can still see bits in the pics after a long soak and good scrub), the design, colour, shape and finish dont look particually recent to me either? they have a very 30's to 50's feel to my mind.....Be great if someone could point me towards a similar modern ZBs piece.
Can we move and maybe retitle for other opinions please Mods.
