John, Do you have a way to measure the ring gauge? You can use a ruler to check the length. If the size has changed I can update it in the database. Sometimes CI isn't exact and sometimes the sizes will be changed over time. I would use the one Bruce linked though.
Corona Cigar lists it as 5.75x52, do does Holt's and JR. I do know there has not been an extension of the line to create a new size.
That's a great cigar either way, enjoy!
