I'm eyeing what would be my first Gibson Les Paul Standard, a 2000, with aftermarket Bigsby B5. I've had two Gibson's prior, an SG, and a Flying V. I've played the Les Paul I'm thinking about, and really like it. Almost certainly will be buying it, but I'm curious about the history of LP's with factory installed B5's. In my internet reading over the last two days, I was sure I found a reference to some golden era LP's coming factory with the B5, as unusual as that might be, but can no longer find that reference. So, can anyone fill me in on the earliest known case of an LP being installed with a B5, and perhaps what other years this might have been seen, if at all? I'm just curious.
