Hi Wouter - hope you're enjoying the holidays! Looks like Maverick Music still has the guitar. Take a look at this page from their website, for Gary Moore's '58 Les Paul:

The page mentions having this guitar and the Peter Green/Gary Moore Les Paul together now. I don't see "the" guitar listed on the site, though, so maybe that means it's not currently for sale?
