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 [[stantuffo tuffante|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]]'', ''[[Dunn Camel|Camel]]'' and ''[[Dunn Camel|Baby Camel]]'', ''[[Dunn Senior|Senior]]'' and ''[[Dunn Senior|Senior Jr.]]'', ''[[Society]]'' and ''[[Society|Society Jr.]]'', ''[[Majority]]'' and ''[[Majority|Majority Jr.]]'', and the ''[[Dreadnaught]]'' series with the distinctive openable cap and the [[Tattler]] and [[Tattler|Tattler Jr.]] with transparent barrel.

The ''Dunn'' pens were primarily [[hard rubber]] made; and the company distinguished itself with an extensive advertising campaign. The pump mechanism was simple and robust, and pens were produced in a variety of models from small ladies pens (the [[Hummingbird]]) to the giant [[Tanks]] model, which is sometimes called [[Dreadnaught]] by collectors, although this name rather distinguishes a series that was also produced in ordinary sizes, characterized by caps composed of two parts (another interesting technical innovation, covered by the patent {{Cite patent|US|1596722}}) whose upper section could be unscrewed to reveal the nib but leaving it protected by a protective cage, so you can fill the pen without pressing the nib dangerously on the bottom of the ink bottle.
