      two above pin ? Apparently from a twin as they rods are off set bronze
      (unfortunately missing caps.)

        Many small Johnsons from 1922 to 1938 used 2" diameter rings and offset bronze rods. Lots of them from 1922-1933 used cast iron pistons with 3 rings such as models OA-60, 200, 210.
