Sheaffer - No Reserve Price - Fountain pen

The pen shown in the image is a Sheaffer Snorkel Valiant fountain pen (or similar, such as Statesman or Special) produced between 1952 and 1959.
Main Features
Brand and Model: This is a Sheaffer pen from the Snorkel line, probably a Valiant, Statesman, or Special model, characterized by the white dot (a symbol of quality and lifetime guarantee, if present) on the top of the cap.
Production Period: These models were produced from 1952 to 1959.
Loading System: The distinctive feature is the revolutionary 'Snorkel' filling mechanism. By rotating the knob at the end, a small tube (snorkel) extends to draw ink without staining the nib, then retracts into the barrel.
Materials: The pen is made of pastel grey plastic (also called 'Pastel Grey') with gold-plated finishes, including a wide band on the cap and a gold clip. The nib is probably made of 14-carat gold or palladium.
