Onoto Heritage Piston Filler

The Onoto Heritage Piston Filler

The first fully-functioning Onoto plunger-filler for over 50 years, incorporating a beautiful sterling silver overlay by Henry Simpole, is now available in a limited edition of just 100 pens worldwide.

Innovative and unique

Issued in 3 elegant finishes - in sterling silver, gilded sterling silver (vermeil) and 18 carat gold, each one hand-made in small limited editions, the Onoto Overlay No 1 is a pen with a superb pedigree.

A firm favourite

The plunger-filling system was eventually superseded in the 1950s partly because of the cost of manufacturing such an intricate mechanism and partly because of the fashion for more streamlined pens. However, it remained a firm favourite with Onoto enthusiasts and collectors around the world, and now, following many requests, the recreation of an Onoto plunger-filling pen has become a reality – The Onoto Heritage.

Virtually maintenance-free

This is truly a pen which shouts 'Heritage' at every turn - but with a twist! It has an impeccable lineage and has been developed using original Onoto drawings: the same slim lines; the same push-fit cap; the same plunger-filler vacuum system.  However, key components are now made from better materials than those which existed 100 years ago. For example, the plunger rod is made of carbon fibre; the cup valves are a special silicone rubber and there's an ingenious 3 washer seal that we believe gives a much longer life than the original cork seals. This makes the brand new Onoto Heritage virtually maintenance free.

Huge ink capacity

What’s more, the ink capacity is nearly 2½ times the capacity of a standard K5 converter so you have much longer writing time than most modern fountain pens.

Cut off valve prevents leaking

And, just like the original plunger-filler, The Heritage also features a cut-off valve which seals the ink reservoir when the pen isn't in use. Simply turn the valve by half a turn and it's ready to write! You'll see the similarities between the original plunger-filler and the new 'Heritage' in the poster shown here, reproduced from a 1920s edition of 'Punch'.

Beautiful silver overlay cap by Henry Simpole

Like many early Onotos, the Heritage has a filigree sterling silver overlay. This beautiful art nouveau styled cap was designed by Henry Simpole and includes the word "Onoto" hidden in the elaborate pattern. The silver is hallmarked with the London Assay mark and carries the edition number of the pen.
