In the family desk, in one of my dad's innumerable pencil cases, I was pleased to find two Sheaffer Pearlies from dad's college job with Anderson Erikson Dairy in Des Moines. A little Christmas gift from the company, maybe? Unlike all the other family Pearlies, these have the "Fineline" inscription on the clip.
Compared to Dad's College Pearlie, the AE advertising pencils have less grip at the bottom. Dad's college pencil also has the duel-layer tip, said (in Sheaffer ads) to prevent lead breakage, and also found on the Sheaffer Triumph "Crest" with the gold-filled cap.
There was also a black Pearlie with the duel-layer tip.
That's quite a few Pearlies, with several clip, tip, and grip configurations.
One other Sheaffer I found was Dad's fountain pen I remembered from my childhood. It turned out to be a Snorkel "Admiral." It has a lovely 14 k nib. Still working, too.
