I ordered the pattern on Etsy. It was the only one she had. I paid $17 (plus $2 shipping) for it, which is a little higher, but it is a discontinued pattern.
Here it is on Amazon:

Kathy...what a beautiful sewing machine! My Mom has one sort of like that. It belonged to her great grandmother. She did use it when I was smaller but I am not sure if it is still in working order or not. I need to ask her. I would love to have it in my own home one day.
