An acronym for Société d'outillage Mécanique et d'usinage d'artillerie, SOMUA was a firm that produced tanks and artillery to trucks and buses. 

The Somua JL 19 model was launched in 1955 as the successor to the earlier made JL 17.150. Since Somua as a firm was having losses, the brand was taken over by a rival firm Saviem, who continued to use the same model labelling it as the Saviem JL 19. Produced until 1959, nearly 1300 trucks rolled out of the factory, near Paris. 

Gondrand is a firm that was started by two brothers and began transport operations way back in 1866, in France. The company still exists today and is a major logistics operator with a turnover of nearly 500 million euros (in 2019).
