Vintage Billings #7727 Double Box End Wrench 5/8″ x 9/16″ Vitalloy USA

Vitalloy Box-End Wrenches. By 1949 Billings had changed its wrench styles again, adopting a flat or slightly convex shank instead of the depressed panel design. The markings for the new design were all stamped instead of forged (for the offset models), and typically the “Billings” and “Vitalloy” trademarks were placed on opposite sides of the shank.
