This is a very nice, 1950's era, vintage 3.75" long, offset ratchet screwdriver, marked "STANLEY MADE IN U.S.A. YANKEE NO. 3400" on the handle area. It has a very good working ratchet system and two position switch, for clockwise and counterclockwise ratchet movement. The double slot screw type tips are in very good condition, this tool is very clean, with about 90% plating intact, and works great! We do note a very slight amount of nickel chrome plating is pealing off, around the Stanley logo area mostly. A very handy tool to have on hand!
