Description Esterbrook model W Renew-Point Demonstrator Desk Pen ca. 1948 in Black. Early version with imprinted barrel. These pens were for dealer use in showing the different Esterbrook renew-points. The pen features a special section with a brass clutch enabled to easily swap out nibs. There are no threads inside the section and no cut out for a lever. This would simply be used as a dip pen. Very scarce piece of Esterbrook history. No nib included.
