On the older system the glass sits on a runner gripped by a rubber strip whilst the newer type have holes in the glass itself. The system shown on the "howstuffworks" link relates to a window that is straight on both sides - not seen for donkeys years. I think you would have to visit a museum for an example or at least a classic car rally to find one.
