Here's a good video about Carl Buck's Cabin Waco on floats:
1937 CF-BBQ Waco Bi-Plane (2008) from Matthew Garand on Vimeo.
The blurb is: "Antique plane makes a historic journey back to Anglin Lake where it serves as a bush plane delivering goods from Prince Albert to Buffalo Narrows. It was piloted by Jack Greening whose brother George remembers going for many trips in the bi-plane tracks down the current owner [Carl Buck] and convinces him to bring the plane for a visit."
