The size is apparently undisclosed, but it feels similar to a Bach 5G when played. I bought it about two years ago. I think it was around the time the 5V started circulating, and the size was just right. I bought it because of its rarity and the reliability of Greg Black, but it was expensive, so I didn't use it much and just kept it stored away. There are no noticeable scratches on the shank, and I think it's in pretty good condition. Thank you for your consideration.
