Slotted in the back are the original instructions. There are two original ink cartridges slotted in the back of the box (see photograph). Pen cartouche is not engraved.
Inside, the metal cartridge holder is engraved: with the parker logo and made in u. No marks but i think it is a gold filled pen. It was being promoted by selfridges as a very special parker pen. I thought that the promotion said that selfridges had exclusivity at that time.
The instructions are stamped with the selfridges address and with the 24th december 1980 date (see photograph). I bought it as a gift. I think it may have been tried out (not sure) but definitely not used again since christmas 1980. I don't know if the cartridges are still useable.I have not tested the pen. I think it is a good item for someone whom collects fountain pens which are complete with original box.
