In 1929, the Parker saw the design change of the entire Duofold line becoming streamlined. This Parker Senior has the White on Blue Lapis coloring, it is gorgeous - some of the best I have ever seen.
I have ultrasonically cleaned the NIB, feed, section, cap, and barrel. Replaced the old sac with a new, properly sized Silicone sac. I have hand polished the Gold Filled Parker Clip, 2-Ring Cap Banding, and 14K Parker Duofold NIB. Cleaned, Buffed, Polished and Waxed the barrel, blind cap and cap to bring back the vibrancy and to protect the celluloid of the fountain pen. This Parker Duofold is the Senior Size and measures 5 1/4" capped and 6 1/2" posted.
The fountain pen cap, barrel, and blind cap are in magnificent condition with no chips, cracks or repairs. The Cap has a Gold Filled Parker Clip that has been polished to shine brightly - there is a touch of wear at the top of the clip near the "P". The cap banding has been polished and displays a bright gold filled color displaying absolutely no wear. The barrel is crisply and clearly stamped with, "GEO. S. PARKER DUOFOLD MADE IN U.S.A. PATENTED". There are no monograms or personalizations to either the cap or barrel. The barrel and cap have magnificent color matching with no darkening.
This Senior Streamline Duofold is a Button Filler and has been tested with water and fills as it should. The filling unit operates as it was originally intended.
The Parker NIB is 14K with a PARKER DUOFOLD PEN imprint. The actual writing portion (iridium) of the 14K Parker NIB has a fine point measuring roughly .57mm when measured with digital calipers. When writing a sample with this NIB, it writes with a fine to medium stroke/line. In the writing sample provided, the fine line measures at .57mm with light pressure and the medium line measures at .87mm with firm pressure when I measured with digital calipers. The nib writes extremely smooth. The writing sample was done with the actual pen in the images that is listed for sale. The writing sample was used by dipping the NIB in Parker Quink Blue Ink.
Any specks of white in the images are from the cotton that I used to clean the barrel and cap.
This is an Iconic vintage Parker Duofold Fountain Pen in the Streamline Senior Size. This is a magnificent example from Parker with clean and vibrant lapis coloring in the White on Blue pattern. I would consider this Parker grade in Excellent+ condition - if there wasn't that tiny bit of wear on the clip this would grade in Near Mint condition. This Parker Streamline Senor Duofold is in ready to write condition or just add it to your writing arsenal collection. Certainly, this is a collector-worthy writing instrument.
