What vintage aircraft was registered as NC7210?
My step grandfather, Roy Danischefsky, purchased the Ryan B-1 Brougham #157 NC 7210 in Sept 1928 from Mahoney-Ryan Aeronautics for Midwest Airlines (Wisconsin). He flew it for Mid-West as a private charter and to promote flight as a new transportation option. Here is a photo of him in front of the plane.
Also - Here a photo of the plane from San Diego Air and Space Museum Archives

Where is this plane now? I would be VERY EXCITED to know that it is still exists. Many of these planes did not survive.
