The original vid was longer, 15 min, and called "Spar Pole" Done up up Longview, Wa. The original film had views from several different angles and trees. That saw was a Homelite EZ. A late 60's model I'm pretty sure, because I bought a Super EZ in 72. At the time it was the lightest saw going for a climber. Then the Mac 12 came out shortly after I believe. Real piece of junk.
