Looking for any information on the forge markings on this wrench, an L inside a square. Based on where it was found, it may have been forged in the Jersey City-Bayonne, NJ area. An unusual shaped wrench, with the handle perpendicular to the crescent portion. This came from the basement of a home that had a couple old-timey firefighters in the family tree (late 1800s, early 1900s), so this is maybe an old hydrant wrench?
The only "L" forge or tool markings I could find were for Lakeside (forged with keystone shape border), Larsen (stamped with hex-shaped border), and Lewis (a modern company that makes gun parts), so those don't seem right. Any ideas are appreciated.
