In 1938, Parker, not usually known for lever-fill pens, had two such models occupying the very bottom of their lineup, the Parkette and this pen, the Duo-Tone. The Duo-Tone was made only in 1938 and was the first Parker pen with a metal cap and plastic barrel. It sold for $1.75 and the matching pencil was $1.25 with a choice of either a brushed gold or silver color cap on a Jet (black) barrel. The pen featured a "Visometer" windowed section and the same clip design as the Parkette. It was not successful and was gone by the 1939 catalog.
