It's a Genesis Gold. I'll give Weber a call.
Those are very cool. It was the last of Weber's "old style" grill frames to survive their new design language. I've always liked them.
It's worth fixing, man, if it's not going to cost you half a new grill to do it. Be nice to Weber on the phone, and they'll help you out. It might not be free, given the age, but it'll be informative at the very least.
If you find it's just not worth it, a trip to their website will show you the brand new Genesis, and it really kicks ass; especially as a rotesserie.
Mine is blue:
They changed the design a little while back to put the controls on the front, rather than the table like I've got. That's getting rid of a bit of quirky charm, but it makes much more sense.
Cheers,
Kennith
