The first question is: Why do I call this pen by two names.Without getting into the legal details, it is my understanding that Parker initially named this pen the Signet, and due to this name already being used by another fountain pen, they changed the name to Insignia.Here are the Signet/Insignia and a Flighter from my collection. In an article about her famous brother, it is stated: “O’Connell, named for his Lenahan grandfather, recalls in a book he wrote about the law firm on its 100th anniversary that .” The senior O’Connell believed that the spoken word is all too soon forgotten, “no matter how powerful and eloquent.” “You must always write them down to keep them from being lost and to ensure they will be preserved for future generations,” the father urged his nine sons and three daughters-Joseph F.Jr., Lenahan, Frederick P, Finbarr, Marisita, Kevin, Brendan, Meta, Lelia, Conleth, Diarmuid, and Aidan.I dip a pin into the paint and get a small amount on the pin head.I then touch the pin head in the diamond and the small amount usually fills the diamond perfectly without spreading over the edges. The date code is located on the barrel, at the point where it meets the trim ring and the hood.I used a debutante sized diaphragm on this 51 and the re-installation went well.I polished the cap and nib with metal polish and the barrel, cap, and hood with scratch remover/polish/ and wax.

In any event, I find it is always interesting to search for the names that I find imprinted on pens from time to time. In this example, I was able to follow a story that included a famous Boston legal and political family, including brushes with John Kennedy and Teddy Roosevelt.I guess the lesson is that if you are seriously chasing down an elusive pen for your collection and you find an imperfect example, you may want to take it home and wait for the day when another imperfect pen has a different problem, and the parts can be traded out.This set came to me in a trade for some extra parts that I had in my possession.The pen presented no particular problems other than the need for a new diaphragm and general clean up.I thoroughly cleaned all of the parts above, paying particular attention to the barrel and any stray pieces of the old diaphragm that always seem to stubbornly stick to the barrel, just inside the top where the vac filler sits.
