I assume that's at Whites Farm supply? If so I saw it out in one of their sheds years ago (2004), they had already resorted it.
I went in there looking for some blades for an original that my dad had. Put them on the counter and the young kid working there looked at them and assured me they didn't come off a cub cadet. The older guy working with him just grinned, knowing exactly what they were off of. Then he invited me on the shed tour.
For laughs and giggles, did you check out the serial number on the original sitting next to it? If it's the one they had back then, it's a pretty special machine.
