Set of two Parker 51 Aeromatic Black Resin Fountain Pens

  
This Parker 51 Aerometric fountain pen, believed to have originated from a private estate sale, features identifiable markings inside the ink well. Its nib is crafted from steel, though the precise size remains undetermined. Accompanied by its original box, possibly dating back to the 1940s, this pen measures approximately 4 inches in length. Notably, the ink is dried, and the exterior exhibits faint markings. Additionally, one of the markings reveals a small dent, with a stone visible on the top of the pen.
