Well, i picked up a neat vac-fill Parker 51 at the show.And, yah, i understand "batch variation" for colors and such, but this charcoal-gray 51 is waaaaay different from Dove Gray or Navy Gray. It is the first pen i've seen like this, or at least first i've recognized.
Will have to post pic when have photo access again. This one really is something. Zeelions of 51's i've seen and this is the first extra-dark gray.
1946 production. Disturbingly similar to Parker VS color. regards david
