heh heh heh I need to make the Mysteries section more obvious I think

(Added to my ever-increasingly long to-do list.

The blue set we have a pic of here
http://www.glasstrinketsets.com/Gallery/displayimage.php?pid=1204 has an atomiser base with a metal collar but is missing the bulb assembly - did the one you saw match that or was it a different shape? I'm trying to visualise the "hexagonal cross-section atomiser" you mentioned and am failing (it's been a hectic week and my brain's refusing to play ball today).
The interesting thing for me with this set is that lovely caramel colour, instead of the more usual amber we see more often. One day we'll find them!
