Recently sold on eBay (not by me!) is a pair of clear / yellow stained candlesticks:
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=170396294658 which I've not seen before, but I do have a double pair with the same base and similar features in clear only. (Pics of mine will be added when I get back later - have to dash out again now! :cry:)
I've gone through Pamela's catalogues and site and can't find anything like them. I have seen one of the Rosice (SU) sets with a similar staining so that's a possibility, but is there any other maker in the frame too?
