I am only guessing, but perhaps the Maine State Museum may be of help with your request for information on lumberjack boots.  I remember seeing a 1920s film there of men working logs down stream in Maine.  The owner of the lumbering or milling operation had a brand-new camera and was camera man for the movie.  Not only did he have the camera, but he also knew the process.  Hopefully, he included footwork in the film.  This was all part of a “Made in Maine” exhibition that I assumed was a permanent exhibition.  Perhaps there are some boots in the collection.
