Also in the second half of the '30s Columbus started producing models with transparent celluloid that allow to see the ink level, according to the new trend inaugurated by Vacumatic. From this this period was the birth of the Columbus 112, a plunger filler model. In 1938 the company obtained a patent (nº IT-288327) for a screw piston, which had as a consequence the creation of the 100 line, equipped with a piston filler loading system.
