Around the [[1935]] a new faceted [[Columbus Extra Faccettata|Columbus Extra]] was introduced. The pen was a [[lever filler]], and remained in production until the late '30s. The pen was produced in three sizes, large, medium and small, identified by their initials as [[Columbus Extra G]], [[Columbus Extra M]] e [[Columbus Extra P]].<ref>from the italian "Grande" (big), Media (medium) and "Piccola" (small).</ref> It was produced in two version, with three rings or with a greek motif decorated band. The pen was a [[lever filler]], with a wheel clip, similar to the one used on the [[Doric]], and virtually identical to the one used on the [[Omas Extra|same name]] model produced by [[Omas]].<ref>although there are no specific documentary references, is a known fact that ''Eugenio Verga'' knew and had friendly relations with ''Armando Simoni''; the pens produced by ''Columbus'' and [[Omas]] have in many cases, materials and finishes virtually identical and because this many conjectures have been made, such as the fact that [[Omas]] may have produced for some times some ''Columbus'' models, or that the two companies have made joint purchases from the same suppliers.</ref>

Also around [[1935]] the Columbus introduced a new arrow clip, an obvious imitation of the one used by [[Parker]] on the [[Vacumatic]] model. The new clip was progressively used on many different models, but it was applied primarily on the top models marked ''Extra''. Around [[1936]],<ref>according to Letizia Jacopini, but this 1935 [[:File:1935-Columbus-Extra-Torre.jpg|advertisement]] is already reporting the new location.</ref> as a result of the good commercial success achieved by its pens, ''Columbus'' moved its activities into the new headquarters of Via Lamarmora in Milan, where more space allowed to meet the increased production needs.

In addition to the top line of the various series marked ''Columbus Extra'' the company also produced lower price pens simply marked as ''Columbus'', also identified by a numerical code. In the production of the second half of the '30s stand out among these the [[Columbus 3x|30]] and [[Columbus 55]] lines. Around [[1940]], even if there is who gives the origins to the second half of the '30s, the [[Columbus 25]] was introduced to a compact pen with a  stylized spear-shaped clip using a [[button filler]] system. Although not marked as top line, the pen was provided with very elegant band decorations on the cap, similar to those found on the top models of the ''Columbus Extra'' series.

Also in the second half of the '30s, according to the new trend inaugurated by [[Vacumatic]], [[Columbus]] started producing models with transparent celluloid that allowed to see the ink level. In this same period there was the birth of the [[Columbus 112]], a [[plunger filler]] model. In [[1938]] the company obtained a patent for a screw [[piston filler]],<ref>Letizia Jacopini in his book report it as n° 288327, but this number is too similar to the previous one, {{Cite patent|IT|268327}}, date ten years befor, and this make that number dubious; the only one other known patent is {{Cite patent|IT|102094}}, found on [[hooded nib]] models produced after WWII and marked [[Columbus Extra 148]] and [[Columbus Extra 150]].</ref> which had as a consequence the creation of the [[Columbus 10x|100]] line, equipped with a [[piston filler]].

During the period between the late '30s and the beginning of the '40s, the company was affected, as for all other European producers, by the effects of the war, and because of the economic difficulties and the supply shortage a drastic simplification of production was made, using only [[button filler]] and arrow clip on all models. In [[1941]] the company launched a model produced exclusively for the army, the [[Columbus 29]] that after was also distributed on the overall market.
