Chauffeurs being trained to drive the Silver Ghosts and Phantoms were instructed to leave the clutch pedal depressed just a fraction of an inch by using a stick propped against the seat, even if the car were just to be left out of service overnight. Problem was the clutch plate sticking even if a TINY amount of rust formed on it between uses.

A friend's '33 Packard had the same problem with rust forming on the clutch plate...once we broke it loose, adopted the "stick" trick, and no more problems.

Have double-clutched on '50s MGs and also on some American cars from the '20s, before synchromesh. Nice to know some vanishing skills. How many out there still know the unique method of driving a Model T?
