My daughter in NM just bought a 1910 machine that Singer says is a 15-30. It is in a small table with a knee control and has no cord. I would get her a cord for it if I knew what configuration it has, but she has no internet and only a cell phone, so don't get ahold of her often. I also would like to know if this machine is full size, 3/4 size or ????. I have a 15-90 and a 15-91, but can't envision what this 1910 machine is about. I am assuming that the motor was after-market, but really have no idea. Any help anyone can give will be greatly appreciated.
