Antique Adjustable Monkey Wrench Offset Head Worm Gear 10-12 in Vintage Tool

A classic antique adjustable monkey wrench in the traditional offset-head style. This all-metal wrench features a serrated sliding jaw, worm-gear adjustment mechanism, and a flat bar handle with a rounded grip end. The head is angled in the typical monkey wrench configuration with a fixed upper jaw and a sliding lower jaw. Estimated overall length is approximately 10-12 inches based on proportions. The tool is entirely iron or steel construction with no rubber or wood components visible. Patina and surface rust cover the entire piece, giving it an authentic aged character consistent with early-to-mid 20th century manufacture. The adjustment mechanism appears to still function. A trace of green paint or oxidation is visible near the jaw area. This would make a great addition to a vintage tool collection or antique shop display.
