I doubt that machine is $5,000+ for a new one. Adler no longer makes the thing, not since the 80's. Anyhow, I believe the true manufacturer was Pfaff. Adler name, but Pfaff made. Pfaff, Adler, and Ferdinand all had identical machines of one kind or another at one time. And the 1/2 inch is the foot lift. Put that much under there and the machine probably will not work so well.
