I don't think the combed 'pattern' on the Czech lamps is exactly the same as mine, but I think they are made with the same enamels if you see what I mean They look slightly less tidy, maybe same manufacturer different maker? The fitting on the the Czech lamps is the same or very very similar to mine as is the one featured on Franks 'not Ysart' site which is on a very similar lamp to the Czech lamps, just a different shape. Of course that could just indicate an 'era' rather than a maker but still..
I did see a vase on ebay US that had the same enamels and pattern but went from brown at the top to a slightly opalescent or milky bluey colour at the base. But it was way out of my £ power for research and also it had an oddly written Barovier and Toso signed signature on the base... I am pretty certain the sig was an addition and unfortunately I didn't keep a link to the vase.
But again I thought maybe the same maker maybe Czech.
But I still don't think they are the same as yours and Pete's or Ivo's...or at least I can't see the similaritie, but I can with the Czech mica lamps if you see what I mean?
Thanks for all your help
I'lll keep looking but I'd really run out of ideas on this one.
