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