Any idea on who made this big wrench? Early sized 3/4 x 5/8, which is closer to 1-3/8th x 1-1/8th. No forge mark, 11 inches long, just says Falcon. A little research shows Mossberg made a light bicycle wrench called the Falcon, and Williams made an early pipe wrench called the Falcon, but no one claims to of made a wrench line named Falcon.
