What you have there is a 1984 Super Record crankset, Nuovo Record BB cups, and of course the Dura-Ace 113mm spindle. All that should work just fine together. As long as your chainrings aren't hitting the frame, and you're using a 6 or 7sp freewheel with 126mm rear spacing anyway. That extra 1.5mm of DS space from the 115.5mm spindle isn't really a make-or-break difference.

By 1984, Super Record cranks were supplied at retail with Nuovo Record BBs, because the SR titanium BB spindles did not hold up well under any but the lightest riders. IIRC they had a recommended 165 lb (75kg) rider weight limit and that was probably pushing it. Fine for most pro racers, but not necessarily your average weekend warrior.
