Pen repair Parker 51 Vacumatic
Parker 51 Vacumatic in Nassau Green
Vacumatic 51
Introduced in 1941, the Vacumatic 51 has a plunger at the end of the barrel which connects to a rubber diaphragm.
The barrel acts as the ink reservoir - there is no ink sac
Pen Repair Parker 51 Aerometric
Parker 51 Classic Aerometric in black
Aerometric Mk 1  -  When one thinks of the classic Parker 51, one generally has in mind the Mk1 as illustrated immediately left with the short arrow clip and rounded end to the barrel. These were in production in the UK from around 1948 to 1972.

The Aerometric Mk 1 holds ink within a plexiglass sac similar to those illustrated on the left, some of which also have black screw-threaded foundation units

These are robust but are generally replaced as part of our standard 51 service

During the service, your 51 will be completely disassembled, cleaned, adjusted and re-assembled before being thoroughly tested

Pen Repair Parker 51 Nibs
A selection of our 51 nib stock
Some of our 51 nib stock.  We have a selection of nib grades including fine, medium, broad and sometimes oblqiues/italics.

51s coming in for service have often been in daily use for 40-50 years and, after such a time, frequently need a new nib

We are experts at nib adjustment, smoothing and replacement

Parker 51 Mark 2 and Mark 3

In 1969, Parker UK introduced the Mk2 which is most easily distinguished from the Mk1 by having a squared off end to its barrel. In the mid 1970s, the Mk3 was introduced.  Both have caps and clips similar to the Parker 61 and illustrate Parker's rationalization of production during the 1970s

There are also many other smaller variations and 'transitional' models, so the classification of 51s into Mk 1, 2 and 3 is very much a simplification
