From 1950 they started to use the lever brewing group with a horizontal boiler. This started with the Rancilio Invicta in 1950 and later with the La Preziosa in 1951. In 1953 the Rancilio Mignon was designed, which was used in bars with little space. The 1955 procuded Rancilio Alpina had the same design philosophy.
