Cool video great history. If you are ever in the area there is a scale model of a PH dragline with all the implements made of wood and tons of other cool things at the hall of fame trucking museum in Canterbury Connecticut. I made a video of the place when I visited I wasn't able to get everything its on YouTube. https://www.youtube.com/watch?v=-J7N76054UU&t=19s. There is a nice display with a plaque explaining who built it and his affiliation with PH. I didn't get a very good picture of it but if I remember right he was a long time employee (I believe engineer)
