I was reading on another list, and someone posted this address:
http://www.sewingshop.com/dateyourmachine.aspx
I went to the page, and found a listing of Singer model alpha, and could click to find the pages I used to access through the singer site. For those of you still trying to access the no-alpha numbers, they are there.
(I think Singer has not taken them off the site, just made them very inaccessible. But I did take the precaution of saving them to my computer...)
I heard that Singer was sold to another company - anyone know if this is true?
