The Parker 51 fountain pen was intended as the pen you would use on an everyday basis. It was meant to be a hardworking writing implement that would operate without any trouble providing the owner with a reliable pen. There was nothing really remarkable in the appearance of the pen with monochromatic plastics dominating the appearance. The nib is a hooded nib that sits mostly within the shell of the pen. The original 51 fountain pens were constructed of DuPont Lucite which was the latest technology in tough plastics.
The Parker 51 fountain pen was released as a number of different versions and may be collected as such. The models of the 51 include: the Mark I, Mark II, Mark III, 51 Special and 51 Special Edition.
Parker 51 Mark I (1941-mid 1960s)
The easiest way to spot a Mark I “51? is to look for a date code. Date codes were put on the pens until the first part of the 1950s, so if there’s one there, it has to be from that time or earlier. Also, pens from 1941 may or may not have a date code, and if it does, the placement is known to vary between the barrel end and clutch ring. On aerometric fillers, you will find that they have a plastic end cap.
Parker 51 Special (1950)
The “51? Special was a lower cost Parker 51 released in 1950. It was designed with the hoop style aerometric filler, and used a stainless steel nib made from “Octanium.” The cap was also stainless and featured a black jewel. It was originally only available in black, burgundy, teal blue, and navy gray, with forest green being added later in the production cycle. The “51? Special was produced in standard and demi sizes.
Parker 51 Mark II (mid 1960s-1969)
In the mid-1960s, Parker began producing the Mark II “51". This version, redesigned to update its look, bears a noticeable resemblance to the 61. Its cap has a 61-style clutch, with fingers bearing on the shell instead of on the clutch ring, but the standard “51? clip is still present. The end of the barrel is squared off to a shallow conical shape that mimics the cone of the cap jewel.
The Mark II still used an aerometric filler, but the sac guard used was modified so that it could be formed from one piece of metal that was formed closed, rather than using a plastic end cap to seal the back of the guard.
Parker 51 Mark III (1969-1972)
The Mark III “51” appeared in about 1969. This pen looks similar to the Mark II. The cap shows the most visible external change. The clip, a new 61-style long Arrow clip, is no longer part of the cap’s decorative trim ring; it is a separate part and the clutch ring was reduced to more of a simple trim ring and was no longer functional in any way.
Parker 51 Special Edition (2002)
Parker released a Special Edition re-issue of the “51" in 2002. It had a unique Empire State cap in silver and gold, and was a cartridge/converter filler, rather than the original vacuumatic or aerometric.
