Translations:Dunn/6/en

All Dunn fountain pens were produced using this particular filling system, which also characterized their style; the back of the pen, used as a knob of the pump filling system was carried out in red plastic (initially in hard rubber, then replaced by casein, a perishable and lower quality material), so it formed a distinctive feature of the pen, that in another slogan was described as "The fountain pen with the red pump handle". A series of models of different sizes were produced, named (in size increasing order): Hummingbird, Camel and Baby Camel, Senior and Senior Jr., Society and Society Jr., Majority and Majority Jr., and the Dreadnaught series with the distinctive openable cap and the Tattler and Tattler Jr. with transparent barrel.
