Free Stanley Transitional plane. Liberty Bell series. Maybe a no. 122. Base is 8" long x 2 3//8" wide. Iron is 1 3/4" wide. Unique two piece cutter screw with a notch which engages the adjustment nut. Good for parts or a "wall hanger". Not usable as a plane because of a crack in the iron and a crack in the metal base. All other parts seem to be ok.
