The Tabo series of late 30's were produced in different versions depending on the filling systems as there are button filler models, called Mentis, and depression filler models, similar to the Vacumatic, called Trasparente, as well as models with the more ordinary lever filler with a faceted body, similar to the Omas Extra, identified by the number 1931. Finally there were also safety models, made in hard rubber or with metal overlay, very similar to those found in the Montegrappa production, named with a four digits code number.
