You are all right...I didn't realize it was a zipper foot even tho I know what they look like. I did buy a replacement "regular" foot for when I sew with it. I have to get brave and thread "Grace" this weekend. I have the pamphet but the pictures are so small in it. I will have to "study up" on the tension dials etc. I'll keep you all posted.
When I started this collecting habit one of the first machine I bought was a 99 with no case thinking I could find one. Did not know a good case was worth more than the machine. I will have to to make a case some day. Very nice job.
