Hello, I recently found a 17 year old music-makers gothic harp. it has an “outer stress fracture” on the neck, as the seller referred to it. I tried to attach a picture of the crack that the seller sent me, but after four or five tries, I gave up. The seller stated that the crack was only cosmetic, and that it would not affect the structural soundness of the harp, and that it would not grow any bigger. I wanted to ask if this was really cosmetic and if it would get any larger. Thank you very much.
