Yesterday I come across with an Antique shop not far away from me, then decide to get in to have a look. The where a lot of mixed stuff and I decide to ask if there are any vintage pens. A nice lady come forward with Parker 51 box, also with some Cross ballpens. I had a look on the 51 and I asked to dip the pen in a bit of water to test it, it has having some dried ink. After like 2 minutes the pen start scribbling something and I was happy. The price? £20.00 with the original box and instruction leaflet. I come home and flush the old dried ink (brownish to dark blue...) left for 5 min to dry and fill with a blue ink mixed of Parker Quink and Diamine Sargasso Sea, then realign the nib and now the pen is writing like a dream. I love the color, the size, the weight, is perfect balanced, a dream pen. Near to the ring has PARKER, Made in England .6 I cannot figure about the date based on the dot 6 imprint. Some pictures now:
