Default Integrated bb's and cranks

Something I just can't get a clear picture of :
With the new confections of external bb bearings and their associated
cranks, are BSC cranks interchangeable in Italian bb cups and vice versa ?
If it's a silly question to you, I'm not surprised, considering its source.

I would be very surprised if they were not interchangeable. I
installed quite a few BSA external BB bearings and once they are in the
BB shell I can't see anything special looking at the cranks.

I wondered about axle length.

There are always some spacers included. I had to use one for a Ultegra
FC6603 triple crankset I installed last week.

not silly. In Campagnolo one crank/spindle slips into either BSC or ITA
cups. The cup thickness allows for 68 or 70mm shells.

Yes, take any crank, use the applicable BB cups for the frame...but
there are not BSC or ITL cranks, yet.
