CNN has a story on Douglas So and the F11 Photographic Museum in Hong Kong that has many Leica cameras on display (I reported about this museum on Facebook few weeks ago):
Among F11 Photographic Museum’s collection is a display of 60 Leica cameras — each with their own story and history — including a 1954 Leica M3, which according to So, is one of the most popular cameras Leica has ever produced.
