Wow only just seen this post, I can't believe this instrument went back into circulation ?
I was the original owner who returned it back to Ken Timms after I highlighted the error on the fret markers.
Ken did replace the instrument for me and I am happy with the Cuban mahogany Soprano I now have.
Just a note, you won't need a serial number to identify that one. The fret markers were way off, not an OCD thing on my part, although I am an engineer and like things to be correct but a blind man on a fast horse would notice it.
