Nooo not the shed Paul, it's much too nice and erotic for the shed!
Definitely not technically safe to include it as Walther Prismen, I just wanted to throw it out there for info really, I will adjust my photo album title since the labels were only on the pots and yes Anne, it doesn't seem to match the catalogue drawings properly, it just seemed such a good match looks and colourwise I thought it was worth mentioning. You're right Anne there appear to be a lot of small differences in the two set portrayals, even the candlesticks look different now I look again, with the Lib ones seeming to have some grooves on the cup, and the Walther pots appear to come to a point (or have a tiny blob) at the top of the finial too.
As you say Paul, it would appear that Walther would have taken from Libochovice if anything, but another thought occurred to me, did Libochovice make anything much in this satinised type finish? I've seen photos of a few sets on Ebay in the style, but always in the clear shiny type colours, and the photos have never been good enough to make any judgement on the pots sticks or ring holder, the tray however, has always seemingly had the single starburst amount.
We definitely need some photo comparisons. Anne I think possibly your mystery set 41 (Lib tray maybe?) http://www.glasstrinketsets.com/cms15/index.php?option=com_content&view=article&id=198:mystery-set-41&catid=28:mysteries&Itemid=52
and 58 (Prismen sticks maybe?) http://www.glasstrinketsets.com/cms15/index.php?option=com_content&view=article&id=214:mystery-set-58&catid=28:mysteries&Itemid=52
could possibly be tied in with these two sets also.
Paul, nice Mary Candlesticks! You had a great boot sale day there with the Pelican finds too, well done! There are two types of Mary sticks, 1936 and 1937, the 1936 catalogue is here, http://www.pressglas-korrespondenz.de/aktuelles/pdf/pk-2002-3-2-mb-walther-1936.pdf
page 17. Your shape ones do appear with oval and rectangular what appear to be Roland trays, and some as yet unidentified pots that could well be Mystery Set 50. http://www.glasstrinketsets.com/cms15/index.php?option=com_content&view=article&id=206:mystery-set-50&catid=28:mysteries&Itemid=52
and sometimes flanking a clock. I have the same sticks in clear uranium which came with what appears to be a Roland tray also, pics still in the camera at the moment. Thanks for the compliment by the way, but I'm no photgrapher, I just take loads of pics and choose the best ones!
I'll await your rummaging with anticipation Anne, I'm also trying to get hold of some comparisons myself.
