It's a 114W or 116W. Model will depend if bale width is 14" or 16". It doesn't have twister hooks similar to current wire balers to twist the wire when tying a bale but twister boxes IIRC it tied a bale on each end of bale IE 2 twists per wire. This machine started the story that sq balers left pieces of wire in/on hay bales because it indeed did do that.
