A Waterman's Ideal #5 in 14k gold from late American production, the 1930s into the 1940s, stamped "Waterman's Ideal 14k."
The highlight here is hairline first. At rest the tines lay a 0.15mm EEF cross stroke, finer than most dedicated needlepoints and more even than a modern Platinum UEF. The tipping geometry is tight, with precise tactile feedback under the hand. Under 360g of moderate pressure, a true Flex on the scale, the tines open to a 0.86mm BB for a 5.73x range. The top end reads measured; the fine, even cross stroke is what defines the nib. Very nice strong snap.
The tines are sharp. Past full flex they will cut paper, and the EEF profile wants a light, controlled hand on the upstroke to keep the hairlines clean. Aligned and heat-set before seating, the tipping smoothed and the base given a light burnish. Sits in Nikko black ebonite on a JOWO #6 ebonite feed. B+ for honest writing wear, the imprint crisp and legible, the structure sound.
Tested on Rhodia 90gsm ivory with Diamine Imperial Purple.

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.
