This line was joined by a more refined line, derived from the [[lever filler]] [[Minerva Ellittica]], also produced this with unusual colors for the original version. As further evidence of a production left largely to [[Omas]] there were also some [[Ercolessi]] pens derived from the [[Minerva Classica]], both in the [[lever filler]] and [[piston filler]] versions, also distinct from the different celluloid colors and the presence of three rings on the cap.

Alle linee in celluloide si affiancarono pure delle versioni [[rientranti]] decorate con elaborati [[overlay|rivestimenti]] in metallo, di nuovo denominate secondo lo [[Numerazione Waterman|schema]] di [[Waterman]] con i numeri 42, 42½ e 42½ V, di probabile produzione [[Columbus]]. Sempre di produzione [[Columbus]] era il modello denominato ''[[Velox]]'', simile ai modelli [[Columbus Extra]] lisci, con clip a rotellina e due anelli di diverso spessore sul cappuccio.  

Celluloid pens were joined also by [[safety]] versions decorated with elaborate metal [[overlay]]s, again named after the [[Waterman]] [[Numerazione Waterman|pattern]] with the numbers 42 , 42½ and 42½ V, that were probably made by [[Columbus]]. Alsa the model called ''[[Velox]]'' was [[Columbus]] production, similar to the round [[Columbus Extra]] models, with wheel clip and two rings of different thickness on the cap.  

Solo a partire dagli anni '40 la collaborazione con [[Omas]] e [[Columbus]] cessò, probabilmente a causa delle difficoltà negli approvvigionamenti di celluloide. Allora la [[Ercolessi]] si rivolse alla [[Ancora]], che produsse per l'azienda dei modelli con [[caricamento a stantuffo]] denominati ''Ercolessi 62'' e ''Ercolessi 65'',  derivati dalle versioni economiche della [[Lusso]].
