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.

Still in [[1937]] the company, until then directly owned by Isaia Levi as a sole proprietorship, was transformed into a public limited company, which is why a new joint-stock company was founded, the [[Sapem]]. (acronym for ''Società anonima penne e matite'') to which was conferred the ownership of the ''Fabbrica italiana di penne a serbatoio Aurora''.

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 [[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.

Nel [[1948]] la [[Sapem]] passa sotto la guida di Giovanni Enriques, nipote di Isaia Levi; questi era entrato tre anni prima nel consiglio di amministrazione, ed era diventato azionista di maggioranza a fine 1946, dopo un aumento di capitale; nel 1948 assume anche la carica di amministratore delegato. E' lui l'artefice del rilancio dell'azienda, che in quello stesso anno recupera in parte la ragione sociale originale, diventando la Aurora Società per Azioni.  

In [[1948]] [[Sapem]] passed under the management of Giovanni Enriques, nephew of Isaia Levi; he had joined the board of directors three years earlier, and had become the majority shareholder at the end of 1946, after a capital increase; in 1948 he also assumed the position of managing director. He was the author of the relaunch of the company, which in the same year partly recovered its original name, becoming ''Aurora Società per Azioni''.  

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]].
