Vintage Snake Chain or Flexible Metal Tubing

This object is a long, flexible metallic segment, commonly referred to as a snake chain in jewelry or flexible armor tubing in industrial applications. It measures approximately 15 to 24 inches in length and is constructed from interlocking circular metallic segments that allow for significant multi-directional flexibility while maintaining a circular cross-section. The material appears to be a base metal, likely brass or steel, with a dull silver-toned plating that shows age-related wear and oxidation. The construction mimics the biological structure of a snake's spine, providing a smooth exterior surface. Notable features include the absence of end caps or a clasp mechanism, suggesting it is currently in an unfinished or salvaged state. The condition is fair, showing visible signs of surface pitting, tarnish, and slight kinking in certain sections where the interlocking parts have been overextended. There are no visible maker's marks or stamps on the outer surface. Based on the patina and construction style, it likely dates from the mid-20th century. The quality is consistent with mass-produced mechanical or costume elements, serving as a functional component rather than a fine jewelry piece.
