Where it all started 1908

Here is earlier history: 20 years before the British claim.

 In 1877 Russian inventor Fyodor Abramovich Blinov created a horse-drawn tracked vehicle called "wagon moved on endless rails", which received a patent the next year. In 1881–1888 he created a steam-powered caterpillar-tractor.

 


Holt/Caterpillar make many claims but they were 30 years behind the others who had mastered differential steering while caterpillar were persisting with a road wheel for steering.
