In the first half of '20s the [[Columbus 670]] model, very similar to [[Waterman 42]], was introduced. It was produced in three size, normal, thin, and ladies, and in black, red or [[mottled]] ebonite. The range of available [[overlay]]s was also expanded, form the simple engraving machine were added to decorations or bas gallery and this work became one of the strengths of the company. There is a remarkable production of this pen with an engraving of the star of David on the body of the pen (also listed on the packaging) as a result of an agreement between Columbus and the ghetto in Milan.
