Condition: 
The pen is in overall very good condition with nice color on the cap and the typical darkening on the barrel, there are no cracks or personalizations.  The clip is firm and the Parker imprint is readable. The double ring gold filled cap bands are solid with a hint of wear. The barrel imprint has some wear and is mostly readable, as shown.  The pen has been cleaned, a new ink sac installed, it has been water and ink tested.  The pen fills nicely and writes well.
