It’s windmill Wednesday, Windmill Junkies Unite 🤘🤘
This sectional windmill engine is an old 1860’s design through 1910 or so,,,,,, I don’t know when this one was made but it’s old and complicated lol.
Known as a Dempster number 3….. vaneless, self regulating for the speed of the wind so it turns the same speed over a certain point.
