Dating parker 51

Parker should be a familiar name to anyone who pays attention to pens; their Jotter ballpoints are everywhere, and they have a pretty good reputation in the higher end as well.

They were (and still are) one of the great fountain pen companies, and the arrow clip design should be instantly recognizable to anyone who pays attention to fine pens.

The Parker 51 featured a number of technical and design innovations.

The nib was concealed under a hood, leaving only the point exposed.

During the 1920s and 1930s, this was the button fill mechanism, which used a button hidden behind a blind cap to compress the bar that the lever would have compressed.

The Duofold, introduced around 1922, formed the top end of the Parker line through the 1920s.

This limits air exposure, increasing the length of time you can leave the pen unused and uncapped before the nib dries out.

The small tubular nib is encased in a collector with numerous thin fins (all concealed under the hood) that acts as a giant ink trap, further lengthening the uncapped time by keeping ink near the point and also regulating temperature and pressure changes more evenly by acting as a large buffer.

The Parker 51 was first introduced in 1941 and displaced the Vacumatic as Parker's top end pen.

For the first decade or two of its existence, the 51 was one of the world's most sought after luxury prestige pens; Parker advertised it as "The World's Most Wanted Pen." Parker marketing pushed the 51 in ads during World War II even though production could not meet demand, which only furthered the exclusive and desirable image they were trying to cultivate.

Parker went into the cartridge pen business with the Parker 45 "Convertible" pen, which is still in production today essentially unaltered in design (parts from vintage and current 45s interchange cleanly).
