As is normal for Parker 45s, there is no barrel imprint,  the cap being clearly stamped around the cap rim "PARKER   MADE IN ENGLAND". It  has the characteristic Parker chrome plated arrow clip. The medium tipped nib is in very good condition. The nib unit is stamped simply "M" (= medium) and can be readily unscrewed and replaced with a nib unit of other characteristics.

The pen is fitted with a  Cartridge Converter. If desired this can be removed easily and Parker ink cartridges used instead.
