Ray H. Allen travelled widely from the 1940s to the 1970s. Many of his tours were with the National Automobile Dealers Association (NADA) and the Wisconsin Alumni Association. We have no specific evidence of who did the filming, except some which refer to Mr. Allen as making the film. There may be some credits. Those that have sound have this noted on the cannister. Some of the cannisters have a notation that the scripts is inside but we have no knowledge of their location.
