I bet you wished you had never asked, now
As a rule of thumb, you can call an American pilot anything you want at first as he either won't be listening or if he is, he won't understand anything you say. As they say, two nations divided by a common language.
For what it is worth, I would call him 'November one zero zero alpha bravo' and wouldn't bother abbreviating it. If I was absolutely satisfied that the pilot had a full understanding of English with a slight Yorkshire accent, I might consider abbreviating it to 'November alpha bravo' which, according to 5milesbaby's MATS Part 1 (CD edition) is wrong but I'm too stubborn to change...
