Buttery is the word for this nib. It is a stub-ground Waterman's Ideal #5 that stays smooth at every point in the flex cycle, backed by a feed set juicy enough that the line never starves mid-flourish.
Un-flexed, you write a medium downstroke against a finer cross stroke, so ordinary handwriting picks up decent variation on its own. Push forward with deliberate pressure and the tines open to a 4B swell past 1.5mm, close to a 4x spread, and they return with a gentle controlled snap.
The nib is 1930s to 1940s production. Waterman stamped Ideal on its nibs for half a century, and the #5 sat in the middle of that range, large enough for a full swell and the size modern conversions favor. This one is set in a black Nikko ebonite JOWO #6 housing and drops straight into any pen that takes a #6 unit.
Tuned at the bench with the tines aligned and the tipping smoothed to a polish, then heat-set over a matched ebonite feed and run through a full writing test. Graded B for light use wear, the imprint clear and the nib original and sound.
Tested on Tomoe River 68gsm A5 paper with Pelikan 4001 Brilliant Black.

Appendix for Listing Details
Sweating the details is fundamental to understanding, appreciating, and knowing the peice of history you have in your hands.
All pens are filled and tested, not just dipped in ink, which does not reflect writing characteristics whatsoever.
Line Variation Standard
Different restorers have different standards for line sizing and especially for vintage pens, the printed tipping size will not always be accurate due to repairs/grinds/etc. Please use this as a frame of reference for consistency.
Flexibility Standard
Nib flexibility is such a controversial topic, but there needs to be some level of consistency so please take this table as a frame of reference for my restorations and as someone who is writing in a calligraphic/spencerian style of cursive script. Without objective measurements, flexibility terms such as wet noodle are useless as someone with stronger forearms and grip strength will make even manifold nibs into a wet noodle.
