In the middle of '40s ''Columbus'' introduces the [[Columbus 13x|134]] model, a big [[lever filler]] pen that was a clear imitation of the [[Eversharp]] [[Skyline]]. The same model was also produced in the [[Columbus 13x|132]] medium size version and in the [[Columbus 13x|130]] small version, for ladies. Again in the '40s a [[piston filler]] model, the [[Columbus 40|40]], was also produced and the [[Columbus 55|55]] had a restyling, becoming a whole line of pens.
