Parker 51 Vacumatic filler in Navy Grey with gold filled cap. Parker transitioned the Dove Grey colour when they started making Aerometric filler pens and began using a darker grey called Navy Grey. While Vacumatic fillers can be found in both colours there are far less in Navy Grey as they seem to have been made for a short period during this transition. This example has a later style gold filled cap with arrow clip, often found on 1948 made pens and a fine 14k nib. Overall fair condition with good colour, some dings to the cap with slightly larger impressions on the underside of the clip.
