What to Look For
Cone-cap eyedropper with #3 nib. Less common than the ubiquitous Model 12 (#2 nib) or Model 14 (#4). The Peyton Street Pens identifier lists examples with 18k gold-filled band and clip in BCHR (black chased hard rubber). The #3 nib is an intermediate size between the standard #2 and the larger #4.
A cone-cap eyedropper with the intermediate #3 nib size. Less frequently encountered than the #2 (Model 12) or #4 (Model 14) — the #3 was a mid-size that saw less demand. The Peyton Street identifier documents examples in black chased hard rubber with 18k gold-filled bands and clips.
