I have ultrasonically cleaned the NIB, feed, section, breather tube, and barrel. Replaced the old diaphragm with a new, properly sized one. Hand polished the Split Arrow Clip, Chevron Cap Banding, Blind Cap Tassel, and 14K NIB. Cleaned, Buffed, Polished and Waxed the barrel, cap, blind cap, top and bottom jewels to bring back the vibrancy and to help protect the celluloid. The Emerald color of this Parker is stunning.
This fountain pen cap and barrel are in excellent condition with no chips, cracks, teeth marks or repairs with the cap always securing tightly to the barrel. The cap has the Gold Filled Split Arrow Feather clip and the Chevron gold filled cap banding that displays no brassing. The top and bottom jewels are black and have been polished to a beautiful shine. The barrel imprint is good, but the date code is non-existent and reads, "Geo. S. Parker Parker Vacumatic Made in U.S.A.". The transparency of the barrel is excellent as one can easily see through the barrel, albeit with mild ambering. There are no monograms or personalizations on the cap or barrel. This Parker Vacumatic Fountain Pen measures 4 5/8" in length capped and 5 3/8" posted.
This Parker Vacumatic filling unit has been greased and now operates smoothly and works as it was intended to. Typically in my tests with water about 5 to 7 presses and it will fill 7/8 full.
This Vacumatic has a 14K Parker NIB with a fine point measuring roughly .53mm when measured with digital calipers. The NIB has a date code 1 for 1941, which dates the pen to this era. When creating the writing sample, the thinnest line measures at a fine (.46mm) stroke and flexes up to a (.1.42mm) double broad stroke when measured with digital calipers. The 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-Black Ink.
Any specks of white in the images are from the cotton that I used to clean the barrel and cap.
This Parker Vacumatic Shadow Wave is gorgeous. This Vacumatic Shadow Wave would grade in excellent condition. It is in ready to write condition or just add to writing arsenal collection.
