23 years young.
Now, that all my parts are off my Marinoni frame, I've photographed three images of my chrome fork. Note the small faded out Columbus decal... I'll be receiving a new one from Marinoni. And, I'm proud to say that my chrome forks are in excellent shape. The Peninsula Cycles mechanic mentioned that my Campy headset is in good shape and only the 23 year old ball bearings require replacement!
