Great stuff! You're right about the wheel wobble and vibration, perhaps that's how he got his name!
There are separate machines for flying and water, I think the autogyro might be a Wallis, as in Wing Commander Ken Wallis (of top Boffin ever, and James Bond fame) or it could be a Campbell Cricket. I love autogyros, and Wallis is an incredible person. He made a huge and very rakish/pimpish sports body for his Rolls Royce, fitted with 1/2 million candle power searchlights for headlamps.
Like the shots of Rio too. One of my earliest memories was calling there on the way to Montevideo and taking the cable car up Cocovada mountain, and looking up at the statue of Jesus which disappeared into the clouds. Somewhere in that series there is almost bound to be a shot with a Messerschmitt, Heinkel or Isetta in it.
Off topic perhaps, but many thanks for that!
