When one thinks of the vintage Parker 51 pen, one generally has in mind the Aerometric Mk1 as illustrated below with the short arrow clip and rounded end to the barrel.This model, with many variations, was in production in the USA and UK from around 1948 to the late 1960s In 1969, Parker UK introduced the Mk2 which is most easily distinguished from the Mk1 by having a squared off end to its barrel and a Parker 61 type clip. The Mk1-3 classification of the Aerometric 51 is useful as a guide, but is a great simplification as design changes, driven both by technological improvements and the need to reduce production costs, came about throughout the 51s production period.

It has been assumed that Parker began marking some of their pens on the trim or cap bands to allow for dating in 1970.

Using the words "Quality pen", one letter per year, followed by a quarter marker, allowing for dating within a ten year span.

In 1894, he invented and patented his "lucky curve" feed system, which greatly reduced the leakage that was a common problem of early eyedropper fountain pens.

By 1905, Parker’s Lucky Curve pens were a force to be reckoned with in the growing fountain-pen industry. Its cap could be screwed down to the pen’s body, making it ink-tight.

This pen is identical in construction to the Duofold - eventually, Parker included Jade as part of the Duofold line.
