The latest issue of Collectible Auto arrived today, with a nicely illustrated article on Buick in the ’30s. Auto writers assume every reader knows the basics of engines and transmissions and suspensions and differentials. Writers will explain unfamiliar antique technologies like sleeve valves, wood-framed bodies, magnetos, and free-wheeling. They always get free-wheeling wrong.
This explanation surprised me:
Fisher No-Draft Ventilation was added to closed-body cars throughout the GM lineup in 1933. It used large pivoting vent windows that allowed passengers to individually control airflow without directing uncomfortable drafts to other occupants.
Okay, now I’m old.
