The hydraulic window system was standard equipment on the 1941 180 closed car models. This system differed mechanically somewhat from the post-war system in than it required the pump to reverse in order to lower the windows. The post-war system simply opened the valve and let the window retraction spring lower the window. I think this is due to a difference in the design and interaction of the pump gears.
