Parker 51 demonstrator fountain pen – Up here is a vintage Parker “51” fountain pen, DEMONSTRATOR version, which was manufactured in USA circa 1940s.

Demonstrators were made by Parker for salespeople, so as to demonstrate the use and functionality of the pen with sample. It is not common in the market hence it is highly collectible.

The Parker “51” went into production in 1941, and remained a best-seller for decades thereafter. Perhaps no other fountain pen has been so unanimously acclaimed as a classic. Nor is it merely a triumph of styling – though it has a place in the Museum of Modern Art’s design collection, and Lazlo Moholy-Nagy found it worthy of praise – for it is also one of the most robust and practical writing instruments ever made.

This stylish Parker “51” series has been manufactured in stunning DING-FREE lustraloy cap gold furniture, with a blue diamond on the pocket clip.

The barrel, including the body, filler cap and section are clear transparent barrel. You can clearly see the vacumatic filling system.

This Parker “51” has a classic elegance and has been produced to the highest standards of craftsmanship, technology and aesthetics. This is rare and very much sought after, of such a collectible and vintage pen in nice conditions.

This Parker “51” is in Mark I MKI version, with overall length 5-1/2 inches.

The Parker Pen Company was founded in 1888 by George S. Parker, whose mission was to manufacture a better pen. The Parker Pen Company’s tradition epitomizes the highest standards of craftsmanship, technology, and aesthetics. From the 1920s to the 1960s, Parker was No.1 in worldwide writing instrument sales. The Parker Duofold is one of the most recognizable and enduring fountain pen designs. Launched in 1921, the pen was a phenomenal success and put the Parker Pen Company squarely into the front rank of fountain pen manufacturers. Duofold remain popular in Europe being produced well into the 60s in varying sizes and colors when it was revived in the 80’s once again as Parker’s Flagship model.

In 1932, Parker began test marketing the next generation in fountain pens, the Golden Arrow. This radical new pen featured a compact plunger-operated pump filler that nestled at the back end of the barrel, eliminating the space-hungry pressure bar and sac. The Golden Arrow was later renamed as Vacumatic. The Vacumatic went on the market in 1933; and discontinued in 1939, due to the introduction of new Aero-metric filler.

Parker pens were frequently selected to sign important documents such as the World War II armistices, and commemorative editions were sometimes offered.
