It has one slight piece of damage to the top which is very hard to see unless the light is just right. I tried but it is difficult to photograph. You may pick it out in the last photo in the listing.
This classic instrument has an even, warm tone but is not loud with these strings but holds its own when using an amp. All metal strings are louder but not as warm as the nylon cores. I suspect the numbers'in the wild' would be in the 100's and this model has been out of production since 1996.
