Parker 51 Nib Change
The Parker 51 is a highly collected pen, revered by pen enthusiasts around the world. First introduced formally in 1941, it continued in production into the 1970s. Over the years it had different filling systems (Vacumatic and Aerometric), was produced in many different countries (USA, Canada, Great Britain, Argentina..), and in varying sizes, colors and styles. The history is rich and for further research there is a very comprehensive book titled Parker 51, by David and Mark Shepherd.
I have several Parker 51s and have always enjoyed them. My only complaint, if I ever had one, was that most of the nibs were very similar - fine or medium. These pens did come with other nibs, but they are uncommon on pens that one finds in the wild.
I finally took the plunge and purchase a broad stub nib for a Parker 51, produced by Greg Minuskin. His website can be found here and he specializes in re tipping fountain pen nibs. I had read about his work and seen an example on one occasion.
I thought it would be a good opportunity to take some pictures of a 51 / Aerometric opened up as I changed out the old fine nib for my newly purchased broad stub.
Below, you can see the components. The sac assembly was working well, so I did not take it apart. As you can see, there is a lustraloy cap, blue barrel, matching blue hood, badly stained collector, nib, feed and attached breather tube.
I took the opportunity to clean the collector, feed, breather tube, and old nib (which I can use on another pen). The hood unscrews from the aero assembly. If it is difficult to unseat, gentle heat is a good solution. Be certain to unscrew as it is not a friction fit. The breather tube can be cleaned with a fine wire, if it is clogged. The collector and feed are easily cleaned in and ultrasonic cleaner.
Here is a picture of the new nib - a juicy broad stub. It simply fits over the old feed and the breather tube attaches back to the feed in the hole at the end of the feed. The feed is reattached into the collector which is reinserted into the sac assembly.
Here it can get a bit tricky. When the hood is screwed back on to the pen, it may not align perfectly with the nib. You may have to pull the feed and nib out of the collector to move the alignment to the hood.
Here is a picture of the nib after it has been fully set in the pen. The broad stub lines are a treat to use.
