Need guitar EXPERTS! Savona SN-20 made in Brazil?

My grandpa ped away a couple months ago and we were cleaning out his basement. I found and old guitar case and opened it up. There was an old clical guitar in it. The tag on the inside of the guitar says Savona model # SN-20. Made in brazil. I have researched everywhere and have not been able to find much information. I read somewhere that a guy found some info on one that says its worth around $2000 cause it was made out a rare wood only grown in Brazil. The wood was abundant in the area, but there was a bad wild fire and destroyed almost all of the trees. So the price of the guitars sky rocketed. I am not planning on selling the guitar, but I would like to know some more information on it, if anyone has any info I'd really appreciate it. Thanks.
