Very interesting.
I saw one of those (or something ver y like it, I dodnt know what it was) in a shop window in Brussels, when I was a student, this was in the 1980s.
I was haunted by it, and next day decided to go back and see what the price was.
I could never find the shop again. Brussels is like that.
I remember that to this day. that feeling of should have grabbed it when I could.
