I don't know! Right now, I have my 1973 Singer touch&sew sitting here, with the gear that operates the feed dogs GONE! It was rubber & broke off! Was willing to let it go, couldn't use any of the decorative stitches , the core that holds the cams is cracked & not replaceable.Was told at last cleaning, she was on last legs! ready to let go, THEN my sister says, "you could just quilt w/it-NO FEED DOGS!"hmmmm, funereal delayed, BUT now(2mos) I think its time to say good bye!
