Antique Brass Barrel Key Collection Set of 8 Keys and Ring

8 heavy cast-brass/bronze keys is a genuine relic of the Industrial Age. Unlike modern replicas, these keys show no machine mold lines (seams), indicating they were hand-finished during the late 19th or early 20th century. Their "barrel" design was once the standard for high-security cabinets, trunks, and interior mortise locks.
​The keys feature a variety of mechanical bow designs. They possess a deep, natural aged patina, making them perfect for Steampunk art, industrial decor, or historical display.
​8 unique keys on a large vintage-style split ring.
Circa 18701910.
​Heavy cast brass/bronze alloy (non-magnetic).
​Hand-finished; no modern factory seams.
​Condition Statement
​Overall good antique condition with a rich, dark patina. Note: One key shows a historically broken/chipped bit (teeth); the exposed metal at the break shows less oxidation than the surrounding surface, confirming it as a genuine mechanical wear-point from age. All other keys are structurally sound.
