Ralf-Stetysz
Ralf-Stetysz () was the marque of one of the earliest Polish car manufacturers begun in France and transferred to Poland in the 1920s. It was formed in 1924, when Count Stefan Tyszkiewicz, an inventor and mechanical engineer, started a small automotive firm "Automobiles Ralf Stetysz" in Boulogne-Billancourt near Paris. The name was an acronym in Polish of the name "Rolniczo Automobilowo-Lotnicza Fabryka Stefana Tyszkiewicza" - "Agricultural-Automobile-Aero Factory of Stefan Tyszkiewicz").
