WTB: Colnago Super Pista Fork

Hi, im looking for a Colnago Super Pista Fork like this one in the picture for my restoration project. I hope somebody can help me.
Preferably 200mm steer tube length for 58cm frame height c-t but I would be also happy to find a shorter fork-then I would try to solder it.
