Yes, thanks, I tried there a few months ago. Not even the slightest suggestion in reply!
The green is good for WF (e.g. the crystal-cased green optic vases of the early 60s) but the blue doesn't match Arctic or Sky, and I don't know of any 6-lobed WF pieces. That doesn't mean there weren't any, of course...
Oh, no! It must be one of those rare experimental items again... :-)
