Eagle eyed bidders noticed that the tensioner was not installed. I search the sewing room and found a bag full of parts in the new picture. I dont know how to assemble it but it looks to have the parts for one and a half tensioners! My wife used the machine all the time but did no...t know how to do maintenance and I know less the nothing (i think sewing machines are some kind of voodoo) i cannot guarantee the tensioner is all there but I can guarantee all the pieces in the picture are included.
