Not necessarily at all. It was manufactured in 1966, you are assuming that it is a student "Director" model which would likely place it as being made at the ex BEST Manufacturing plant in Nogales, AZ. However, if it is a pro "Artist" model from the same year of production, it will have been made in Elkhart, IN.
Crystalh,
Since you are unfamiliar with saxophones, and what to look for to positively ID this horn, you will need to provide clear and complete photos of the entire horn to confirm.
