Oh it’s nothing that grand. It’s simply a private stock build made to replicate all the Paul’s 28 features but is a 24 fret Custom 24 Stoptail. Therefore it was just privately named as Paul’s 24. It’s not a run of 24 guitars. Thus my tongue in cheek post. Brilliant concept by the original owner though, and very sporting and gracious of Paul to lend his name in that manner. It’s definitely a special guitar, a back-in-the-day thing!
