I recently aquired this guitar. It is in perfect condition, no nicks or scratches and everything is in like new. It has been stored for nearly thirty years. I am an amatuer guitar collector but have been unable to find any information. I normally do not collect classical guitars, but there was something about this one that was interesting.

Can anyone help me out with finding info on a Savona SN20 made in Brazil about 30 - 40 years ago?
