VINTAGE GIBSON GUITAR KNOBS

Buying this Ibanez guitar?
Hey im buying this vintage Ibanez electric guitar. The seller wants to sell it for $450 aus its in good condish. Im pretty sure the seller said it was a 70’s model. It’s an SG type with 3 humbuckers and a horseshoe bigsby 4 knobs. Its exactly like this picture here except black. http://img2.freeimagehosting.net/image.php?11151b3a54.jpg I can’t find much info on this guitar and was told by someone that its possible it was te guitar that triggered a lawsuit with Gibson. Is this a good deal?
Really hard to say, I’ve never seen this model of guitar from Ibanez. But for 450$…Vintage, it’s still a pretty good deal. Ibanez have always made great guitars, (I actually own one as well as a bass).
