Parker. Parker Senior Duofold Flat-Top Mechanical Pencil, Jade Green A vintage Parker Senior Duofold flat-top mechanical pencil in the desirable Jade Green finish, one of the most distinctive and sought-after colours produced by Parker during the Art Deco era. Introduced alongside the celebrated Duofold fountain pens, the model reflects a period when Parker was at the forefront of American writing instrument manufacture. The richly coloured jade material, with its characteristic variation in tone, remains particularly popular among collectors and is closely associated with Parker's production of the late 1920s and 1930s. Designed to complement the Senior Duofold fountain pen, the pencil exhibits the clean geometry and confident styling that defined the flat-top series. Today, jade examples are especially appreciated for their visual appeal and their importance within the history of Parker's most iconic product line. Model: Senior Duofold Flat-Top Type: Mechanical pencil Colour: Jade Green Condition: Good vintage condition. Accompanied by: No box.
