North Mfg. Co. (New Haven, CT) Cast‑Iron Wrench
6″ Size • Patented January 9, 1877 • Schulz No. 373
A scarce and very desirable North Manufacturing Company cast‑iron wrench, made in New Haven, Connecticut, and covered under the January 9, 1877 patent. This is the correct 6‑inch size, a compact and beautifully proportioned example of one of the more distinctive late‑19th‑century patented wrenches.
Listed as No. 373 in Schulz’s Antique & Unusual Wrenches, the North Mfg. Co. pattern is instantly recognizable: a graceful cast‑iron body with crisp curves, a cleanly formed jaw, and that unmistakable early Connecticut industrial character.
