This is a classic Inoxcrom 77 fountain pen, often called the "Spanish Parker 51" due to its similar sleek, aerodynamic hooded-nib design. Produced by the legendary Spanish manufacturer Inoxcrom (founded in Barcelona in 1942), the "77" was the company's flagship model during the 1970s and is celebrated for its exceptional durability and smooth writing performance. The pen features a rich burgundy red barrel paired with a gold-plated cap and clip, which bears the "SPAIN" hallmark.
