I have an american home, model no. 1804-B, serial no. 0922. there was an little wire thingy sticking out of the tension knob contraption that you're supposed to loop the thread through when threading the machine. when it broke, I was told there was no way to replace it.
does anyone here have that part? are you willing to sell it? I'd buy other parts along with it or even a whole machine of the same make and model.
