Yep, just measured adj bolt holes at ~89mm which corresponds to a 151 BCD.
Imagine, a Zeus crankset with some interchangeability - old Campanolo for inner or TA Pro 5 V rings, adapteurs, whatever using the 5 pin...

Zeus cranks as it has a bolt circle which is too large, and it's also bigger
than 70's era Campy.
