This is an extremely rare find in this absolutely mint unused rolled gold Parker Lady Classic ballpoint pen (new refill installed). It was manufactured in England at Newhaven in 1973. I have described it as used so as not to confuse you with the modern version which was made in France. It comes in its original box with leaflet. Unfortunately I snapped one side of the plastic holder on the box holding the pen in place in the box when photographing it.
Im sure this can be replaced quite easily. This would make a very special Christmas present for that special person or of course for the dedicated collector.
