After looking at some models, I think the kind I had when I was younger was the TransOceanic 3000 model.  I found one for sale and picked it up.  It is what I remember; map, time zone dial, pull out book, it even has a distinctive scent I remember (flux or something).  The example I have works, but the dial is off a bit.  I probably won’t use it for day to day listening, but it is in great shape and should be fun to use from time to time.
