(Sold) This is a 1947 full-size Blue Diamond Parker 51 Vacumatic in Cordovan Brown, with a two-tone stainless steel cap, gold-filled trim, and a 14k gold Fine nib. The pen has been restored, which included a complete disassembly, a thorough cleaning, an overhaul of the filling mechanism, ink flow adjustment, nib tuning, and a gentle polish with a soft cloth (by hand).
Having such a huge variety of awesome fountain pens available today (both vintage and modern), it's becoming more and more difficult to put together one's "Top Five" lists of favorites. However, no matter how I shuffle my "Top Five," the Parker 51 Vacumatic is always there, and close to the very top. Apparently, I am not crazy, as the "51" has been "the world's most wanted pen."
To me, what makes the "51" a favorite is its writing performance. Period. Yes, you can argue that it has supreme ergonomics (no step, no threads, a slight taper), and that it comes with a sophisticated, high-capacity filling mechanism, but, at the end of the day, when the rubber meets the road (insert your favorite cliche), and the pen has to perform consistently, at the highest level, regardless of ink, paper, writing technique, the "51" never lets me down. It writes where most other pens refuse to. It produces the most splendid, silky smooth monoline that other pens are jealous of. It is firm, without feeling harsh. It has that awesome, resolute willingness to deliver ink to paper, without fuss, without hesitation.
The pen is in fantastic condition, without any flaws or defects. The material is vibrant, with a deep, rich color, and a pleasant glossy finish. The cap and gold-filled clip are in equally great shape. Truly, a fantastic specimen, and, interestingly, the "last year" model of the Blue Diamond lifetime warranty. The following year, Parker began a transition toward the new variant of the "51," the Aerometric.
