This is tempting
it looks like a reissue custom shop Les Paul, which if genuine is worth £1500-2000+.
But it just screams wrong....its pretty all right but the fret board is too light, the pickup switch is the wrong colour, the control knobs should have a finger pricker position indicator, it should have an aged look on the pups, no case is mention and lack of proper pics on key ID points is odd...Also the price....I mean £475?? If he bought it as a Gibson reissue he'd have paid a small fortune for it...and would be asking for a Buy it now rather than a very low auction starting price.
I've mailed him to ask for specific pics of key points that will help ID it, if he sends them, I'll be tempted...but....something tells me its a chinese copy, and not worth 500quid...200 maybe, but not 500.
