Antique Brass Ship Porthole – Scandinavian Work c.1920 – Crowned Head Mark (Stockholm) – Original Thick Glass – 7.9” (20 cm) Description Magnificent authentic brass ship porthole, circa 1920, most likely crafted in Sweden (Stockholm area). This is a genuine marine fitting, not a reproduction — with its beautiful aged patina and original thick glass, slightly uneven and full of character. On one of the locking screws appears a small hallmark depicting a crowned head, very similar to the Saint Erik symbol, emblem of the city of Stockholm. Such details make this a rare and collectible maritime artifact. Features: • Date: circa 1920 • Origin: Scandinavia (likely Stockholm, Sweden) • Material: solid brass / bronze • Overall diameter: 20 cm (7.9 inches) • Original thick glass: yes • Mounting: 4 screw holes • Mechanism: side hinge + locking handle • Finish: untouched aged patina • Authenticity: guaranteed 100 % original marine piece Perfect for: • Vintage boat or yacht restoration • Authentic coastal home or loft decoration • Marine-themed interior design or architectural reuse Historical note: The crowned head mark corresponds to the Saint Erik emblem — the ancient symbol of Stockholm, used as a quality and city hallmark since the 18th century.
