The bottom lever filler, also called rear lever filler, is a special lever filling system designed by Aurora and used from around 1930 for the Internazionale model, and later used also on the Novum. There are no known variants of this system used by other manufacturers, even if there are several patents with similar mechanisms, except the switch filler of the Pilot, which has some similarities, in particular with the variant of this system adopted later on the Superna model.
