I'm hoping someone with knowledge of recent Gibsons can help me out. There's a 2003 Gibson Firebird VII that I have my eye on. It's not Pelham Blue, but a strange grey-ish blue. Did they make non-custom shop Firebird VII's in that year? The serial number starts 0XXX3, and I thought CS guitars had a different serial system. Is $1800 a fair price for this? Cheers.
