This is a late 1970s/early 1980s Waterman rollerball pen made predominantly from frosted aluminium. It is part of a consignment of pens and pencils from the stock of a stationery shop that closed in the early 1980s. It is still in its original box with its original 1970s shop price tag. It is in near pristine condition. It has the typical narrow but robust chrome plated Waterman pocket clip that they used on several models of the time. The cap is fairly short - shorter even than the pocket clip and it has an imprint around the lip. The barrel end has a black blind cap that you unscrew and remove in order to replace the rollerball refill. I have fitted a fresh refill into the pen. The gripping section is also black.
The box is also in good condition though the foam rubber underlay to the pad has crumbled into a fine dust. I have removed this and cleaned the box out, and replace the pad without the foam rubber.
I don't know what model of pen this is, but it is certainly an unusual find as I have never seen one quite like it. It would not have been an expensive pen, but it is certainly very well made.
