At least in the early years is also known an economic production under the brands ''[[Eridano]]'' and ''[[Eridania]]'', usually accompanied by a model number, and sometimes by the letters ''PCT'', as an acronym of ''Pecco and C., Turin''. The initial production were eyedropper or safety hard rubber pens, in four different sizes. The same mark was used on a later production for celluloid button filler models. It is also believed that the company has produced parts and pen for other brands, and some believe that also the brand ''[[Scriba]]'' is attributable to [[Stilus]].

Si ritiene anche che l'azienda abbia prodotto per altri marchi, alcuni ritengono gli sia attribuibile anche la produzione a marchio ''[[Scriba]]'', di certo è attribuibile all'azienda il marchio [[Eridano]] (registrato nel 1929 {{Marchio|38320}}, il cui uso è confermato anche da [[:File:Stilus-Eridano-Invoice-1937-01.jpg|questa fattura]] del 1937.

During the '30s the design began to be revised, with the abandonment of the ball clip to the adoption of more streamlined lines. The [[Stilus]] production followed the trend introduced by the [[Omas Extra]], with wheel clip and faceted pens, imitating the design of the [[Eversharp]] [[Doric]], which characterizes virtually all the Italian production of that period. In this period were produced lever filler celluloid models named ''Automatica''.   

Nel corso degli anni '30 lo stile iniziò ad essere rivisto, con l'abbandono della clip a pallina e l'adozione di linee più affusolate. Anche la produzione della [[Stilus]] seguì la moda introdotta dalla [[Omas Extra]], con penne sfaccettate e clip a rotellina, imitazione dello stile della [[Doric]] della [[Eversharp]], che contraddistingue praticamente tutta la produzione italiana di quel periodo. Vennero prodotte in questo periodo le penne in [[celluloide]] sfaccettata con [[caricamento a levetta]] denominate ''Automatica''.   

The new multi-faceted models were identified by the digit 10 (resulting in a 4-digit code) while the smooth version were identified by the digit 9. The use of celluloid was presumably indicated by the digit 4 in the column of tens, even if there are model with the digit 5. The details on the numbering of this period are therefore somewhat uncertain.
