Excellent find!
A very under-appreciated offering from Weber.
I prefer this design of JJ as compared to the current design because of the deeper bowl. A great cooker, IMHO.
I had the same rust issues at the leg tabs. I also replaced all the hardware with SS.

Your lid handle appears to be in decent / salvageable condition …. Or, you can go the Zav route ….
and just the name "OutRider" screams bad ass
