Re:
crank arms don't look particularly far up the axle taper, are they tightened on yet? also regarding the length of the axle, you sure it's right? 115 sounds right for the older stuff but those arms look newer, meaning lower profile which would suggest an axle length shorter, say a 110? the more recent tapered axle doubles were running around a 103mm axle which suggests a more recent triple chainset would need around a 110.

Re:
well the simple answer is that the axle is too long, i would try and confirm what year model the chainset is then you can find out the correct axle length.
a couple of pics of the chainset may help

Re:
that's why i questioned whether it was a campag chainset, seeing the old BB on the floor in the pic suggested to me that the BB had been replaced with a newer version of the campag BB which are internal cups on the non drive side.
so basically if you have put in a shimano BB it won't work as the taper lengths/angles are different, which would mean that the crank arm would not go all the way up the axle.
