So, is someone better off with the original vintage 51, say the aerometric version, or is someone better served by the new release of the Parker 51?
I will say that I am still mostly using my first vintage 51 bought in July, 1970. The other 51s I bought are a collection. I don't need a new 51, but I wonder if you think the typical writer would be better off with a pen made in the modern idiom, designed as pens are today, as with a C/C filling system or with an integral filling system like a squeeze filler, etc.
