Filling systems

The top lever filler is a particular lever filling system used by Aurora from around 1930 for the Internazionale model, and later also on the Novum. The first version of this filling system however, was used by Curzon for the Top Lever model (later renamed Debrett's) of 1926. Since the patent of the Top Lever (nº GB-273357 and nº FR-628272 which is even more similar to the mechanism found on the Aurora) is from 1926, it is incorrect to attribute the invention of this system to the Aurora. There are no other known variants of the system used by other manufacturers 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.
