Vintage Celluloid or Hard Rubber Fountain Pen

This appears to be a vintage fountain pen from mid-20th century, likely from the 1930s or 1940s. The pen features a barrel and cap made of a dark material, possibly black celluloid or ebonite (hard rubber), which has been decorated with a series of fine, horizontal gold-toned rings or banding. The grip section leading to the nib is also gold-toned, suggesting it may be gold-plated brass. The nib is visible at the top, appearing to be a traditional metal fountain pen nib. The pen is shown in two parts: the main body and a separate cap or end piece. The condition shows significant signs of age and wear; the dark surface appears dull, and there is visible tarnish or oxidation on the metal components. The fine banding on the barrel shows unevenness, indicating frequent use and potential moisture-related wear to the decorative finish over time. Small scratches and abrasions are visible throughout the body of the instrument. While no maker's mark is clearly legible due to the resolution, the design echoes the 'Golden Web' or 'Stacked Coin' styles popularized by brands like Sheaffer or Parker during the Art Deco era. The construction quality suggests a mid-tier to high-tier writing instrument originally meant for professional use.
