A very interesting pen by Parker. The company called the pen the “61.” It has a cartridge that was attached to the feed of the fountain pen that when placed in the ink automatically pulled ink into itself.  All the user needed to do was unscrew the barrel of the pen from the section which revealed the long capillary filler made from plastic. Insert the filler end into the ink and hold it there for approximately ten seconds. Afterwards, wipe the ink off the filler and replace the barrel.  You are ready to go.  It is strongly advised to NOT remove the filler from the pen.
