Lots of photos on this link of an amazing private collection that it was possible to visit in Italy for many years.  It was quite a feat of Carlo Salterelli, collecting  over the years almost one of every model and making them available on display, first in a beautiful museum and later in a warehouse.  Sadly, the collection will now be scattered far and wide, it's scheduled to go to auction in Monaco in 2012.  For some great photos of the original museum, click the link above.....
