Me, I would probably post it up on one of the bmx sites in the "for sale" section and see if anyone is interested. If not, I'd part it, take the good parts, and give the frame and anything remaining to someone who can use it.

Post more pics when you get it all cleaned up. btw, reproduction decal kits are available if you want to make it factory fresh.
