LARCO Wrench & Mfg. Co.


Larco Wrench & Manufacturing Co. (Chicago, IL) - We find reference to the company in 1918 but have yet to find formation information.  In 1920 the company received the trademark for LARCO.  Registration #131,336 (not found).  The July 29/1920 edition of Iron Age reports that Larco has purchased a forging plant and machine shop at Woodlawn & 78th from the Great Lakes Forge Co. and will move there soon.  In August of 1921, Industry Week reports that Larco purchased the Cochran Mfg. & Forging Co.  We believe the Cochran property was owned by Great Lakes Forge and sold to Larco.  This article notes that Larco will continue producing Cochran products, including wrenches.

Larco Advertisement from June, 1921.
