I have the same. I thought we used singer oil?? I went online and copied the manual. Just cleaned mine up. Need to get a case and the thing by the wheel for bobbin is off. Don't know if u need if if ur not going to wind bobbins? Guess we will be figuring ous out together. I was gonna call mine Lucy for all the trouble she's kinda given me! My 15-91 is Ethel!! U could call your rose Marie!!
