I thought lack of a white dot was common for the lower end pens (which excludes the Imperial line of the 70s since even a 440 steel/plastic model had it) -- the types found in blister packs hanging on hooks in a various pharmacies and office supply stores. Originally it signalled a pen with a lifetime warranty. These days -- with ownership now in Cross hands -- anything goes*.
However, I do not know of such a (lower end) pen in a size that would fit a 70s imperial fountain pen. I believe capped rollerballs were slimmer.
NOTE: NOT a 2444 -- the 2444 has squared ends on the barrel and cap, similar to the PFM and early 60s Imperials.
* The current Sheaffer web site needs to study their own history...
- The Triumph conical style nib is created and the new line included ballpoint and rollerball pens.
Really? 1991? My 727 variant goes back to ~1971, and I have a snorkel desk pen, both with Triumph nibs.
