Thanks you wil-weten and Biagio for the advice. I did end up reaching out to the Dusty Strings, and after having them review the photos, they think that the previous owner stored the harp in an environment that was just a little too dry. As far as soundboard separation, I did thoroughly look over the seams both inside and outside for every body panel, and did not see any separation or cracking. Everything appears to be very solid on the harp, but the bulges on each side where the inner ribs are just worried me a bit. I’ll make sure I keep an eye on the humidity, and if anything else pops up I’ll take it from there.
