PARKER 21 SUPER DEMONSTRATOR FACTORY TEST PIECES

These were probably used by Parker to evaluate some aspect of the 21 design. Each pen has a clear demonstrator type shell. Both have lustraloy caps with chrome trim and have not been used outside the Parker factory.  Never catalog items.

Each pen has a number hand scribed on the filling unit like some other non-production collections I have seen of former Parker employees. #4937 has the number "42" scribed onto the filling unit and #4938 has the number "44" in the same spot. 

A whole tray of these were found by David Isaacson after he moved to Janesville. In this town he could search out finds like these.
