In the '50s, following the market trends set by [[Parker]] with the success of the [[51]], [[Columbus]] introduced the [[Columbus 70|70]], an [[hooded nib]] model. In this case however the pen was not just an imitation: it was made in celluloid and used a [[piston filler]], it also had a screw cap, and the nib was only partially covered to allow the us of a flexible nib. Like other Italian imitations of the [[51]], such as the [[Aurora 88]] or the [[Omas 361]] the pen is probably more interesting than the original.

L'ultima serie prodotta in celluloide è stata la [[Columbus 90]] introdotta all'incirca nel [[1951]], e realizzata sia con [[caricamento a stantuffo]] che con un particolare [[pulsante di fondo]] a fondello non rimovibile, simile al ''[[push-knob]]'' della [[Montblanc]]. La produzione degli anni '50 vide l'abbandono della celluloide per l'uso della più economica plastica a stampo, e la produzione di [[Columbus Anni '50|modelli]] con pennino carenato e cappuccio in plastica o metallo o penne scolastiche.

The last series produced in celluloid, the [[Columbus 90]], was introduced approximately in [[1951]], and was made both with a [[piston filler]] or with a special [[button filler]] with the back knob not removable, very similar to the [[Montblanc]] ''[[push-knob]]''. The production of the '50s saw the abandonment of celluloid for the use of cheaper molded plastic, and the production of [[hooded nib]] [[Columbus Anni '50|models]] and other cheap plastic pens for the student market.

In 1957 the founder died, leaving the company in the hands of his son Enrico, but at that time the fountain pen market was drastically shrinking due to the spread of the ballpoint pens. The choice was towards the production for the school and the low end of the market, but the company suffered an inexorable decline. In 1992 the company renmants and the [[Columbus]] trademark were sold to ''Santara Srl'' that is still producing some modern pens under the same brand.
