A vintage industrial padlock of the Scandinavian type, characterized by a rounded-rectangular metal body and a thick, U-shaped shackle. The body is cast from a yellow-toned alloy, likely brass or bronze, while the shackle is made of a darker metal such as iron or steel. The piece features an embossed mark located within a small rectangular recessed area on the crown of the shackle. The mark consists of the uppercase letters SEGAL, identifying the piece as a product of the Segal Lock & Hardware Company. The design reflects mid-century American manufacturing standards for security hardware.
