Here is a link to the 8 millimeter film referred to in Art Wheaton's PARKER PAGES article about George and Kay Evans' visits and their shoots with Dr. Charles Norris.
It is not a professional production, as said at the end of Art's article. It appears that the principals were doing all the filming themselves, home movie-style. But that such a time-capsule of 1950s bird hunting exists at all, showing the dogs, the guns, and these personalities of classic American sporting literature in action, without the guile or bombast of so many contemporary commercially-sponsored hunting videos, accounts for a special rarity and value for enthusiasts.
