 Praga V3S was used by the Czechoslovak Army for more than half a century.Praga was founded in 1907 to build motor cars as a venture between entrepreneur František Ringhoffer and the company "1. českomoravská továrna na stroje" ("First Bohemian-Moravian Machine Works", later a founding part of the ČKD factories).Ringhoffer only stayed for one year and in 1909 the trade name "Praga" ("Prague" in Latin) was adopted.
