Without wishing to defend "NS" and "OS", left and right are problematic as they're essentially relative terms. Do they apply when you're facing front or back? Port and starboard make much more sense as they are always left and right facing the bow of the vessel. One could make a case for "NS" and "OS" provided one could be sure they'd been correctly applied for the country in which they were being used. If I were you, I'd be very nervous that a British supplier had sent decals marked for vehicles that drive on the left hand side of the road (facing forwards).
Sometimes the road not travelled is best left that way. (Jane Goodall)
