I can add some to this thread. I bought an inexpensive Imperial Satellite 127 camera, which had an exposed roll of Kodak Verichrome Pan in it. I needed the spools anyway, for re-rolling 120 film onto. So even if the film turned out to be blank, I was gaining two additional spools. Turned out, the film was intact, if a little fogged. Probably shot in the early 60s. I was born in 1964, so these pics may have been shot before I was born!
Don't know what's up with this airplane.... Mechanical issues?
Easy enough - you go to:

and enter the registration number. N5268B. Turns out it's a 1957 Mooney M20, currently registered to David Cabbage of Colville, WA. Of course, who owned it when the photo was taken is unknown.
