I've watched these cameras as they show up, and that's not common. However, they always go for rather high prices especially when in good shape. I guess I'm just too cheap to get one but I intend to eventually.
I would like to find an intact QRS crank, though. They were so fragile. The seller of the one I have included the pieces of the original but too broken up to recover. A friend back in the States has a great miniature machine shop and fabricates small parts for his model railroad. It would be a labor of love, though.
The Italian Air Marshall of the time, Italo Balbo became famous for organizing a squadron of S.55s for Atlantic crossings, culminating in his 1933 flight with 24 aircraft to Chicago's Century of Progress International Exposition. On 1 July 1933, General Balbo commanded a flight of S-55s from Orbetello, Italy, completing the flight in just over 48 hours, maintaining a tight "V" formation.
I posted in another thread some photos of our visit to the Italian Air Force Museum in Bracciano. Thanks for telling me about it. David
