Exceptionally fine with 90% plus original blue finish, 60% of the lightly fading original case colors, some minor spotting, and generally only minor age and storage related wear. The grip is excellent with crisp checkering and minimal wear. Mechanically fine. The case and accessories are very fine with minor wear. Overall, a very attractive cased set.
