Porterfield-on-floats

I am attempting to capture old 8MM films made by my father, W. R. Skinner (Bill Skinner), when he worked for the Porterfield Aircraft company in the 1930's. I have found a short snippet of film of a Porterfield on Floats. I will upload the video when I find a way to snip it out of the video file.
Thanks, Bill Skinner.
