The Jotter is distinguished by a button and cap made of stainless steel, chrome or another metal, a stylized arrow-shaped clip, a smooth styrene or metal barrel and a metal nozzle. If styrene, the barrel originally came in black, blue, green and red. Over many years of production, the jotter has been produced in numerous colors, some quite rare.
One popular version, scarce in early models, is identified as the laboratory or "flighter" version. These pens have an alloy cap with a matching alloy barrel. The all-alloy bodied pens come with a gold or chrome clip. Another version is the clear barreled "demonstrator", usually sold to dealers to show the inner workings of the pen.
The so-called "girl's" Jotter is a smaller version of the original. It was manufactured in the early sixties and was popular for a time. It came in seven colors (the rarest being brown), as well as a clear "demonstrator".
Also, it appears that the employees would occasionally experiment with their own combinations of colors. These pens have a marbleized appearance and are the result of cleaning the production machinery. If the production run called for blue, and they had been making grey jotters, the last of the gray plastic would blend into the blue creating what were sometimes called "lunch room" specials. These pens are considered quite collectible, but they are usually not "prototypes" as commonly thought.
Management was always trying to expand the market for this pen and commissioned the design department to explore new designs and materials. Several of these prototypes exist and are also coveted by collectors.
There are many variations of these pens and a large collection can be assembled by the serious collector. The variety is endless if a collector includes the advertising variations. All versions of the pen were used in advertising for an endless list of organizations.
The refill comes in ball pen and gel styles, as well as in three point sizes. The pen also comes in a boxed set with a mechanical pencil which is collectible in itself.
In 1958, the company added an arrow to replace the aforementioned ballclip design. The arrow has remained on all production Jotters since then. Occasionally a jotter would slip through with a clip that had no embossed arrows. These are now collector's items. Recent production (English manufacture) have clips in the shape of an arrow, but no feathers
Today's Jotters are similar to the popular, "ruggedized" version that first came out in 1954. More than 700 million Jotters have been produced since 1954 and production continues at Parker's plant in Newhaven, England after being transferred there from Janesville, Wisconsin in 1999.
