I was at the Oldmeldrum rally yesterday with my vintage Sunbeam & spoke to a model T owner there with his 1913 car. He says that both gear change techniques can be used on any age of T. He mostly uses the Australians method with handbrake in centre position & left pedal pressed for low & lever full forward & pedal released for high.
If a 1913 car only needed 2 gears are modern engine inferior if they need 10 gears?
