The only problem with those is that the BCD of the inner ring is non-standard at 100mm. It can be tough finding a ring to fit that BCD, and then the bolts and stand-offs to mount it properly. Campy only made one size to fit, 36T, but there were aftermarket 31T rings that Jim Merz made. All are rare, though. You might try selling it, since it is a factory-drilled triple, as evidenced by the fluting on the spider that stops short of the mounting holes, while cranks drilled on the aftermarket have the mounting holes within the flutes. That might make it worth more to a collector, and you could use the funds to buy a more versatile triple.
