Onoto Plunger Filler – Wet Noodle

Onoto Plunger Filler – Wet Noodle (See Price Here)

Here is a Thomas De La Rue “Onoto” plunger filler. Onoto/ T.D.L.R. is a British pen company that went very early to a plunging mechanism to fill their pens. This Onoto is BCHR pen with the the hard rubber faded to a dark brown. The chasing has been worn almost off, but the imprints are still very crisp. The plunging mechanism has been restored and works well. The 14kt. Onoto nib is covered by an over/ under feed. The nib is a beauty. It is a smooth writing F/XF that writes like a stub. When flexed ink gushes out of this pen, but when not flexed the flow is good but not copious. The flex has a large range going from 0.3mm to 1.9mm (XF-BBB) and is very soft and smooth. These Onotos have an unique attribute. When flexing the ink will eventually start running dry. Then you must unscrew the blind cap and the flow will return, and as I said it will be abundant.
