This early coach or buggy adjustable wrench is a compact and beautifully preserved example of 19th-century European toolmaking. Measuring 7″ in length, it’s stamped “Acier fondu”—French for “cast steel”—a mark often found on high-quality tools produced in France during the 1800s.
• Origin: Likely French, based on the “Acier fondu” marking
• Function: Designed for carriage and buggy maintenance—compact, portable, and versatile
• Construction: Cast steel body with adjustable jaw mechanism

These tools were essential for roadside repairs and fine mechanical adjustments in the age of horse-drawn transport. Their compact size and robust build made them indispensable for coachmen and wheelwrights alike. A rare survivor with continental flair.
