In [[1937]] the [[Superna]] model was introduced, with a variation of [[levetta di fondo|back lever filler]], in which the lever was equipped with a small ball on the outer extremity and mounted vertically in a semi-spheric alluminium structure located on the bottom of the pen. The ink loading was carried out by removing the back cover to access the the lever and operating it through the ball.

In [[1938]], following the  ''visualated pens'' trend  showing the ink level started by the [[Vacumatic]], [[Aurora]] introduced the [[Optima]] model, a [[plunger filler]] made of transparent celluloid, which remained in production until the early '40s. Another model of the same year was the [[Topolino]], a simple [[button filler]] entitled to the Disney character, featuring a Mickey Mouse engraving, and oriented to youth people and students, soon paired with [[Biancaneve]]. From the same period should be noted the [[Iridia]] model and the [[Aurora ML|ML]] line introduced in [[1938]], produced, at least officially, for the armed forces officers.

The company, unlike the rival [[OMAS]], suffered heavy damage from bombing, the plants in Via Basilica were destroyed in [[1945]] and raw materials and archives were lost. But despite this after the war there was a great effort to rebuild the business. At the end of [[1946]], following the new market trends dictated by the [[Parker 51]], [[Aurora]] introduced an [[hooded nib]] model. The design of the pen was entrusted to the architect [http://it.wikipedia.org/wiki/Marcello_Nizzoli Marcello Nizzoli]: the [[Aurora 88|88]] was a masterpiece of the [[Aurora]] production, and obtained a great success.

The [[Aurora 88|88]] model was equipped with a very advanced [[piston filler]], with differential threads. The pen was made with a metal cap in both gold-plated metal or using an alloy of nickel and silver called ''[[Nikargenta]]''. The body was in celluloid with a transparent section, while the handle of the piston was in hard rubber. The [[Aurora 88|88]] was qualitatively and technologically far more advanced than a [[Parker 51|51]], the only plastic part was the sheath of the nib, and the feeder had a sophisticated supply system which allowed a regular ink flux.

In [[1954]] (or in 1957), to counter the massive advent of the ballpoint pens, [[Aurora]] launched the [[Duo-Cart]], a [[cartridge filler]] economic model. The cartridges were carried out in polyethylene, and designed by [http://it.wikipedia.org/wiki/Giulio_Natta Giulio Natta], Nobel prize for chemistry. The distinguishing characteristic of the pen, exposed by the name, was the ability to contain within its barrel a second cartridge, to avoid to get out of ink. Following the same design the [[Aurora 888|888]] was also introduced, a [[cartridge filler]] version of the [[Aurora 88|88]].
