This is a walking foot with a guide. Most of these are made for low shank. I am spoiled by my Pfaff which has built in walking foot, and a guide that fits in the ankle. I hunted around on Startpage all morning and could find nothing.
The heavy duty 1500 does better with quilting. A lot of books recommend a walking foot for straight line quilting, and a guide helps - far cleaner than marking or tape.
I used the Pfaff's guide quite a bit - from rows of spaced embroidery stitches to quilting. The harp on the Pfaff is too small, and foot pressure and tension are controlled electronically.
