Nib Imprint: Parker Duofold 14k Pen Canada
The Duofold is the pen that actually made the Parker Company one of the greatest pen-manufacturers of the world. Until the Duofold few pens were made of anything but black rubber. Parker found a method to make the rubber in a red-orange colour, and when the pens began to sell they really sold. The Duofolds had their world premier in early 1921.
The pen was available only in black and red hard rubber until 1926, when Parker introduced the “unbreakable Permanite” Duofold (Permanite was Parker’s trade name for a plastic manufactured by DuPont).
