This is a Teal Blue Parker 51 in excellent working order. The nib is a nice medium and can be shown writing in the pictures.

The filler has been cleaned and works wonderfully, takes and holds a lot of ink. Will be flushed clean prior to posting.

The box is included and appears in condition.

Nib is in excellent condition. There are no dings or scratches to the section, the barrel has not a single mark on it, no bite marks or anything.

The lustralloy cap is in excellent condition as well, aside from what appears to be some slight pitting on the cap as shown in macro photos.

Other than that, this is a lovely example of a 51, the box is in good condition, given its age as well, a lovely find.

This particular 51 is stamped as being made in England, and has a standard Parker "51" stamp on the Aerometric filling system.

Pen will be packed carefully and sent Royal Mail signed for. Any questions, please free to ask and I will get back to you as soon as I can.
