I have ultrasonically cleaned the NIB, feed, collector, breather tube, hood, cap, barrel and NIB. Replaced the old diaphragm with a new, properly sized one. Hand polished the 1/10th 16K Gold Filled Cap & 14K Solid Gold Arrow Blue Diamond Clip, Clutch Ring, Blind Cap Tassel and 14K Parker NIB. Cleaned, Buffed, Polished and Waxed the barrel, blind cap and hood to bring back the vibrancy of fountain pen and to protect the celluloid. This Parker 51 measures 5 1/2" capped and 6 1/8" posted.
The fountain pen cap, barrel, blind cap and hood are in magnificent condition with no chips, cracks or repairs. The 1/10th 16K Gold Filled Cap has a 14K marked Solid Gold Diamond Clip that has been polished and now shines bright. The Cap has clusters of 9 lines, a cartouche and Deco Banding at the lip. The cap is clearly stamped with, "1/10 16K GOLD FILLED MADE IN U.S.A.". The cap has no major denting and very little light scratches, way below average considering the age of the cap. There is a tiny pinhead ding and just point it out for clarity sake as the last image does show that very small, minor area. The Blind Cap and Gold Filled Cap have the plastic jewels that have been polished to high shine. The barrel is stamped on two lines, "PARKER 51 MADE IN U.S.A. with date code 6 in the third quarter". There are no monograms or personalizations to either the cap or barrel. The clutch ring retains a good portion of the center gold plating.
I have tested the Vacumatic filling mechanism with water and fills as it should. The filling system, typically in my tests with water, will fill nearly full in roughly 7 to 10 presses. The filling unit operates as it was originally intended to and smoothly.
The Parker NIB is 14K and writes smooth. The actual writing portion of the 14K Parker NIB has a fine point measuring roughly .48mm when measured with digital calipers. When writing a sample with this NIB, it writes with an extra fine line. In the writing sample provided, the extra fine line measures at .35mm when measuring with digital calipers. 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 Black Ink.
Any specks of white in the images are from the cotton that I used to clean the barrel and cap.
This vintage Parker 51 Vacumatic Fountain Pen is a gorgeous example from Parker with the marked 14K Clip. I would consider this Parker to easily grade in Excellent Condition. It is ready to write or just add it to your writing arsenal collection.
NOTE: There is no blind cap / barrel / hood discoloration - the reflection off the camera body may give the appearance the color is not matching, but I will assure the color is matching across the pen hood, barrel and blind cap.
