Translations:Blackbird/5/en

Generally Blackbird pens follow the models used by the main brand, of which they share the colour numbering and part of the numbering scheme, but are distinguished by the prefix BB, and at least initially, by the use of only the unit number corresponding to the nib. These pens are generally produced with the simplest of the available filling systems (mostly lever filler), although in parallel to the model Visofil was also introduced a model, the Blackbird Topfiller, with a similar filling system (see patent nº GB-514513).
