This is a good working, clean 1950's era ratchet spiral screwdriver! It is marked "STANLEY YANKEE NO. 130A MADE IN U.S.A.", on the main nickel plated shaft. This screwdriver is the mid-size that Stanley made in regards to tooling, or the tips that fit into the chuck, they are the .280 (9/32") shank diameter size. There is some wear on the screwdriver, about 80% nickel plating intact, with about 20% of the handle paint intact. Some minor dings and scratches noted on both the wood handle, and on the metal. In very good mechanical condition, works great. This one has a rapid return spring, on the spiral system, so it springs back after you push it in to drive a screw. It also had a lever tab control ratchet system for driving or un-screwing screws, and the spiral system can be locked down, or in the closed position for ratchet use only as an use option. It measures 17.5" long overall with no tip in the chuck.
