Sorry, but I didn't get any pics...I stopped at Goodwill today on my way home and saw an old white, metal Singer in a table. It had a built-in cam, was smaller than my 401A, and had a built-in buttonholer. I looked all over it and underneath and could not see a model number. Does anyone have any idea what it is? It is only 14.99, and I'm wondering if the parts would be interchangeable with my 401...thanks

also, it looked like it has the slant shank like the 401.
