This fairly common 6 inch Stanley machinist’s level began in about 1898 featuring fancy filigreed decoration on the sides, and then regressed to a plain nickel plated level early on. During WWII however, the wartime nickel shortage forced Stanley to look for less costly finishes, and the type seen here resulted. The level has plain japanned sides with polished steel frame and bottom, with the brass top plate unplated. The result is a much more interesting looking level. Since the plain nickel finish was restored about 1945, this type was short lived and is fairly scarce today. Fine.
