Miriam, I was looking on the net at different machines and I thought this one matched yours. Here is the picture and whats written under it. (This is another fantastic Visetti. These made by Toyota machines are built as well or better than the popular European brands such as Bernina, Pfaff, Viking, Necchi and Elna of the same era.
This machine now sews in Norfolk, VA.) doesn't look as if it uses cams tho.
