Silvertone Parlor Unknown/vintage - Starburst

Good afternoon, this Guitar appears to be refinished by whomever had it prior to me. It appears to be in pretty good condition. It is strong left handed. a crack plastic of the finger guard , it appears that it was placed there not exactly right therefore it is a gap between the guitar and the finger, also there’s a bulge on the upper part of the acoustic hole. I’m not sure what that is about if you have any more questions about this please contact me. I will ask them to the best of my ability and also I will send pictures if needed.
