I have one of those. It is a reasonably difficult puzzle, quite a nice challenge really.
Mechanically it is rubbish, unfortunately. The tiles are hexagonal, which means they often get stuck when they twist a bit. The mechanism used to keep tiles from sliding unintentionally is also very poor.
The version shown in the virtual puzzle museum won't have those problems. I think that one is a copy of the Equator/Hungarian Globe puzzle.
I do not know how rare it is, or what it is worth. If you want to play with it online, you can try out the page on my site.
