Product Description
Type Fountain pen with a squeeze "Aerometric" filling system.
Product Name Parker 51 Mark IV, different from the Mark III because it has a metal cap jewel that protrudes more than the Mark III jewels. Sometimes called the second version of the Mark III.
Manufacturer and Year Parker, made in USA – After 1973 (1973 is when the metal cap jewels were officially adopted).
Length Full size, 5-5/16".
Filling System Aerometric squeeze filling system. We've tested it and it's working very well.
Color Navy blue body with a lustraloy, satin brushed steel finish, cap with a long arrow clip and a chrome plated cap jewel. The cap jewel is part of the clip and tassie.
Nib MEDIUM gold nib is smooth with nice tipping. It's much broader than what we usually call a fine for Parker 51 nibs but is narrow when compared to modern medium nibs.
Condition Very nice condition. No cracks or chips or deep scratches aside from a deep scratch area to the left of the underside of the nib (see photo below). General wear on plastic, but no cracks. There are very few shiny spots in the lustraloy finish, but no dents on the cap. The trim and imprints look great. It's working very well.
