We have an extensive range of nibs and other parts in stock which enable us to service and repair virtually any vintage Parker 51 pen including Vacumatic and Aerometric versions
We were trained and authorised by Parker and Waterman to repair their products and specialize in older models which Parker have classified as 'obsolete'. We have spent 20+ years repairing pens such as the 51 and acquiring spare parts stock from around the world
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
Aerometric Mk 1
When one thinks of the classic Parker 51, one generally has in mind the Mk1 as illustrated above with the short arrow clip and rounded end to the barrel. These were in production in the UK from around 1948 to 1972.
Parker 51 Custom in Cocoa with some plexiglass sacs
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
Some of our 51 nib stock
We have a selection of nib grades including fine, medium, broad and sometimes obliques/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
Please note that we do not sell 51 nibs
Aerometric 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. The Mk3 shell and barrel threads are coarser than the Mk1/2, and parts for the Mk3 are now unavailable.
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
