Rare Waterman No. 420 red hard rubber fountain pen with sterling silver Art Nouveau filigree. A very large and impressive instrument. The number 20 is the biggest pen ever made by Waterman. The nib is also the biggest Waterman nib. Number 10. A really stunning pen. The No. 420 is differentiated from the far more commonly seen black hard rubber No. 20 by the lovely red hard rubber body and elegant sterling silver filigree (the “4” is Waterman’s code for silver overlay pens). It is said that due to the pen’s massive size and attendant expense it was only available as a special order. The No. 420 is a legendary Grail for collectors of early American eyedroppers; research suggests that as many as three and as few as two examples survive.
The pen is fitted with a slip-on type cap and has a shoulder-less section. Filigree engraved “WATERMAN’S IDEAL FOUNTAIN PEN / STERLING / BERT HART,” endpiece marked “4 20”. Sterling Silver Clip marked Clip – Cap Ideal Pat. Sep. 26.04. Large gold heart-vent nib engraved “Waterman’s / IDEAL / New York / No. 10”. Matching red hard rubber feed. 168mm long, 20mm wide at base of cap. Excellent condition (normal signs of time, some minor scratches), crisp imprints.
