This Model 510 is straight stitch only.  The shiny thing near the balance wheel is a magnetic seam guide I forgot to remove before the photo session.  (Scroll down for more Lelia photos)
Lelia Series
The 513 below has manual zig zag and a buttonhole stitch.
The top-of-the line Lelia was the 515 below.  Not only does it have the zig zag and buttonhole features of the 513, the little door in top accepts drop-in cams for automatic decorative stitches.  One of the cams is shown on the table in front of the machine.
