Well, that 'One Prototype' is still under wraps - it's still in the developmental
stages of design, so it must be covered up at all times from the general public's
interested gaze. If you could imagine, however, perhaps 300 of those - with an
offset of perhaps 1 1/2".
I spotted one on a Mexican beach a couple of years ago - it was also a prototype
and concealed in a different - in that case - a traditional way.
Anyway, that's the tall and the short of it!
