Cheers,
I found the one on ebay by searching for glass + hat which seemed to be a common factor in all the pieces, and just struck lucky...not an easy thing to search for at all.
Only thing I would add for the record is that 'Elena's Imports' who import Czech glassware seem to be based in Canada so may just be unrelated to the 'made by Elena' mentioned in the ebay.co.uk listing, so without a little bit more digging I'm still not 100% sure we can say where these were made, but I'll leave that to someone else.
