The off-catalogue lined wide cap-band commonly is called the Jeweler's cap-band by collectors. It is the most common of the off-catalogue cap-bands. The earliest color to feature it is gray/red.
Grey Pearl (gray/red version) is the only gray color Balance (there ware three colors to use gray) to routinely feature gold-filled trim instead of chrome trim. As we know, chrome trim tends not to hold up as well as gold-filled trim. I have seen some gray/red pens with chrome trim, and as they are a significant minority finding, they fall into the penumbra of the "reverse trim" element of old pens, adding appeal. Of what I'm not sure offhand, is whether there were specific models that were only shown with chrome, which would-- by my use of the term-- remove the pens from the "reverse trim" category. If identical models at identical prices were shown both ways, then even though chrome trim is catalogued, as a very minority finding, I would still consider it "reverse trim".
This pen, a short slender pen, third tier (at least, based on its 3-25 nib) features the Jeweler's cap-band and reverse trim. Very uncommon with this cocktail. This one is very clean, a nontrivial point for this fragile celluloid color with chrome trim. Note the smooth flat-ball clip (sans "Sheaffer's" imprint) a finding seen with Autograph (solid gold trim) and off-catalogue cap-bands
I'll probably end up keeping this one at length, again driving home the painful point that I found too many pens at Ohio that I want for my collection, although thankfully most of the purchases were for the website.
This one... is... really... pretty.
