Sorry no pics yet but I must tell you this.
I was in Auckland last week and invited a friend of mine for a BBQ. He is an avid collector and brought around a few Parker 51's - 48 in fact.
Each one was different including demonstrators a few yellow ones (never seen these before), even a titanium one. I've suggested he posts a pic for all Parker lovers to drool over.
As a side bar he had also a converted briefcase containing about 60 vintage pens of very rare models. I was flabbergasted..I've never seen such mint pens. A real treat to see them in the flesh. I've seen some in books but wow !
A prisitine red hard rubber Waterman with silver overlay was just one I remember.
