Parker was still able to succeed in this area with the popular and ubitquitous low-end Parker Jotter ballpoint, and many generic ballpoints use Parker-style refils.Realizing that the fountain pen market was shrinking but still wanting to preserve an image of luxury and exclusitivity, Parker shifted its pen designs and marketing towards the luxury market with the famous Parker 75 in solid sterling silver.The Duofold line would be de-emphasized in the 1930s in favor of the new Vacumatic line, introduced around 1932.The Vacumatic incorporated a new filling mechanism with a diaphragm at the end that was pumped to draw ink directly into the barrel.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.
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.
Parker was founded by George Stafford Parker in 1891.
Early Parker pens had the unique patented "Lucky Curve" feed, which was an elongated conventional feed that curved back to touch the barrel wall.
Over time, Parker would dispense with integrated filling mechanisms altogether.
Like all fine pen companies, Parker was diminished by the advent of the disposable ballpoint.
