I used to set up triples with Campy Record front derailleurs - they were one of only a few fronts that would work (barely) with older TA cranks. But the chainlines were on the narrow side, your crank is probably farther out than the stuff I worked with eons ago.

Your set up might work well with an older Shimeeno 9-spd. triple front derailleur - 105 to Dura Ace, I think they were the 5503, 6503, and 7703 series ?
One advantage of these is that the cable pull is less than some other vintage fronts, IMHO a help when setting up with friction.
