There have been over 30 nationalities contesting the "World Championship".
Here's my list of drivers' countries:
Argentina, Australia, Austria, Belgium, Brazil, Britain, Canada, Chile, Colombia, Czech Republic, Denmark, Finland, France, Germany, Hungary, India, Ireland, Italy, Japan, Liechtenstein, Luxembourg (arguable), Malaysia, Mexico, Monaco, Morocco (arguable), Netherlands, New Zealand, Northern Rhodesia (now Zambia), Poland, Portugal, Russia, South Africa, Southern Rhodesia (now Zimbabwe), Spain, Sweden, Switzerland, Thailand, Uruguay, USA, Venezuela.
Any advance on 40? Of these 40, over half are in Europe, so very much a Europe-centred 'World' Championship, even today.
