The Sugino Mighty Tour is a top quality 110bcd version of their 144bcd Super Mighty crankset. I know from experience that either will fit the Sugino MW-68 spindle in Sugino's nickel chrome plated cups. This bottom bracket, and the Sugino produced first generation Superbe are virtual clones of the Campy Nuovo Record bottom bracket for English bikes. There is a comparable Sugino Italian bottom bracket. So if you can find the Mighty Tour crank arms I would expect them to work for you.
I have both of these cranksets on different bikes, and I've interchanged them on the same bottom brackets.
The Mighty Tour has model information forged on the *inner* surfaces of the crank arms. They're beautiful pieces.
