I bought one of these too.in the mid 70s Except it had Kizo Suzuki on the head stock. I was polishing it one day and the paint came off and it said Cortez in Mother of Pearl . The dealer I bought it from set it up for me.I have since played a Gibson J2000 Artist which is what the Cortez was copied from and found little difference. In fact the owner found my Cortez faster to play than his J200. I have seen later ones with the neck made up from glued blocks which weren't as good. The only problem I had was electrfying it. In the end I bought a Guild which had the built in pick up but to this day I still have my Cortez which has got smoother by age right alongside my chair.
