Thanks Zed. I have been trying to get this set for quite some time now. I also have a few more, with only one with the special case on the right. The others came with the case on the left. I even got a duplicate as I had forgotten what I had...easy enough to do sadly.
Looking on SAKWiki, I am probably wrong. The first photo is probably the first series minus Gemini, which is probably part of the second run. I have the first Gemini already in a box in the second photograph. Does this sound right?
