Bream’s Romanillos has already been mentioned.
Segovia’s Hauser was in pretty sad shape near the end of its use.
Jerry Roberts (a close friend of Bob Ruck) told me that Barrueco’s famous Ruck had been taken apart and re-assembled by Bob a few times before Manuel switched to Damman.
I’ve seen a few older, well played double tops that were delaminating.A very good guitar maker once explained to me that because the top is supported by 2 layers (DT) and probably nomex, it is less likely to crack or change in any way due to humidity and weather change. That makes me want to believe that they are crack looking braces on JV's guitar as some luthiers explained but again they seem too irregular for that, so...
Bottom line: a well played guitar that travels is going to show battle scars. When I get a guitar back for tweaking that’s been played hard and traveled far and shows it, I consider it an honor.
