I am a fan of Classical guitars, and always game to bring one back from the dead, independent of value.
1. Please look at photo, a funny hole - likely from falling on a metal table, that has been filled with epoxy.
2. I found the instrument strung up with metal strings and this cut into the plastic of the tuner posts. I bought a set on Amazon ($13) and one of the screw holes did not match up. See Photo...I have a thing about not adding screw holes to guitars so left one on each side blank. You can of course drill and add screws.
3. Sorry - No gig bag or hard case.
