I have a question about Necchi's. What is the difference between a Supernova, Supernova BU, and a Supernova Ultra? I picked up a Supernova head yesterday that is green in color, and it is an Italian made machine. It is a BU Supernova. And does anyone know where I can find a free manual? Thank you.
p.s. Miriam, it is already oiled and in it's "Time Out".
