Translations:Dunn/7/en

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 nº 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.
