It would be (or would have been) a good guitar, and it would have an original Edge trem. You need to look out for a few things on a guitar that old, though. Are there cracks behind the nut? A lot of old RGs have them, but you should be wary of any necks with multiple cracks or very long cracks (running towards the scarf joint especially!). How are the frets on her? A fret job can run you 75% of the purchase price on an old RG, so be careful you don't get something that is in desperate need of a refret. The old ones had great stock pickups, so don't everpay for one where the pickups have been swapped out. If it has something you love (like EMGs), then you'll pay a bit more but try not to pay for the pickups as well as the guitar, if you follow. A bound neck generally means a 7xx series guitar, and they tend to go for a little more than the 5xx series guitars. All of the 80's RGs have original Wizard necks as well.
Good luck!
