There did, some manufacturers used to have this as an option as well. Citroën or Volvo from memory. I have seen mechanical louvres on some classics as well.Didnt there used to be a rad muff that was sold with some kind of device so that it could be rolled up or folded from within the vehicle.?
Or was that just another alcohol fuelled dream..?
