I got this from a friend who I worked with for a time after the Parker plant closed in Janesville, he was an employee there.
He just had a lot of extra stuff filling up space and thought I would enjoy them. I always had a Parker Pen in my pocket so he knew I enjoyed having a Janesville-made Parker.
I did some quick research on this. The original refill is there and unused but probably won't work now.
The date code (NI), is last quarter 1979. 
It's stainless with chrome trim Flighter.
It's in excellent unused shape with manual.
My friend would occasionally be gifted items from Parker, they were very generous to their employees.
Has a plain black cap.
I ship in a box not a padded envelope.
