That's not bad at all! Before posting the pics, when you said it looked "relic'd" I was thinking it would be like a lot of the OBG SGs I've seen that were pretty chewed up and either played real hard or not stored/maintained very well or both. Tarnished hardware's no big deal, some guys like the vintage look. As long as it has no playability or sound issues, stays in tune and can be setup properly you're ready to rock on out.
The nitro on the OBGs cleans up very nicely. At least half of all my OBGs needed TLC when I first got them. Usually a good clean up is all I do and leave the hardware until I get tired of looking at it (or just lose the covers altogether like I've done to about half my LPs). Putting on new PU covers, bridge stuff (if it needs it), knobs, rings and/or OEM or upgrade tuners really transforms the way they look. Just doing a fresh setup and new strings on any OBG will blow you away at how **** good these guitars are and not even taking into consideration how well done the fit and finish is, A/B'ing them back to back (sound and play-wise) with any 3-5K+ Am Gibson is shocking.
