Translations:Dunn/8/en
In addition to black hard rubber, Dunn produced pens with transparent barrel; these were initially made in bakelite and later in celluloid. This feature allowed it to boast (rightly) to be the only transparent pen (in the ads showing the Camel Tatler model) to display the ink level, and this well 10 years before the Vacumatic. Are also known to exists, but to be very rare, some metal overlay pens.
