Given that my frame was made in Tennessee I would assume English threading for the BB shell and that the shop where I got the bike would have ordered an English threaded Campy BB .
my confusion is that some old notes that I have say to turn clockwise to loosen the drive side cup and counterclockwise for the other side - does anyone know if this is correct ? seems wrong if English threading on the entire shell ??

FYI. The driveside of an English threaded BB shell has a LEFT HAND THREAD ...
So, to remove the driveside BB cup which has English threading you would indeed turn it clockwise ...
And, counter-clockwise to remove the non-driveside BB cup which has English threading.

You old notes and Alf are correct.
Drive side is a left-hand thread.
Off-drive side is a right-hand thread.
thanks guys !!!
