Parker 51 Aerometric

This British 51 was cleaned up for a friend who has started collecting fountain pens. Everyone needs to have at least one or two 51s in their collection. It’s a pretty standard example of the 51: following the numbering system used by parkerpens.net, it’s a burgundy Mk II-B made in 1955 with a fine, but smooth nib, offering just a little feedback from the paper.
