De La Rue & Co. Ltd. Onoto THE Pen, Blue & Black marble with g/f trim
Around 1928, De La Rue began production of Onotos in celluloid.
The first Onoto – Sweetser's original plunger-filler fountain pen guaranteed not to leak – was manufactured by the Thomas De La Rue and Company Limited in London in 1905. The Onoto pens were an immediate success in the United Kingdom and internationally, and were one of the very few 100% British-made pens prior to WW1.
Condition: Original cork washer, still fills like a charm.
