• FOREST CITY SCREWDRIVER CO. / PAT APRIL 16, 1895:

  The maker marks on this tool usually appear around the upper and lower ends of the shifter barrel inside a zig-zag band. On some models there is no maker mark. This sprial/ratchet screwdriver looks quite similar to early models of NORTH BROTHERS MANUFACTURING CO. "YANKEE" No. 30   The handle is a different shape, it may have one or two shifters on opposite sides of barrel and the chuck may or many not be spring-loaded.
