The new L&K 100 model, which the automobile factory introduced onto the market in 1923, had a classically designed chassis and a SV four-cylinder engine with a cubic capacity of 1771 cc.

The one-hundred and its additional modifications (105, 110 and 120) were top quality automobiles with a good future, but more middle range vehicles  in character than competition for the small vehicles of other Czech makes (Praga Alfa, Tatra 11).

The modernized 110 and 120 models appeared on the market in 1925. Even after the merger with the Plzeň Škodovka in 1925 the 110 model was commercially the most successful. In 1926 it received a more powerful engine (1944 cc) from the 120 model.
