PARKER ARROW CAP ACTUATED BALLPOINT

All plastic. New old stock. I'm assuming Circa 1980 from the box and location they were found in . 

This is one of several incarnations of a pen model named "ARROW" from Parker. See the bottom photo for what remains of a chalk mark on one of them identifying it as such. They came with the inventory of Glenn Christenson's business which was called "The Write Shop", which Dale bought out in 2006. Most of his new old stock was 80's - 90's vintage.
