Thanks 3alarmer, I suspected something like that with this one. I don't know exactly when this crankset was made or even remember how I got it but with my crude measurements and just test fitting the parts together with a Campagnolo crankset it seems to be the same as Campagnolo. I should be able to pick up a Campy spindle pretty easily. Might even have one in the parts box somewhere but I'll have to look.
