nearly free - CH air compressor - U fix it

I have a campbell hausfield air compressor, model wl600602AJ with a bad piston ring - motor runs, the tank is good, the reg and manifold/switch is presumably good, but it won't pump because the piston ring is bad - I figure the tank and wheels are worth something, the rest is free - but I also have a space problem - if you would like it, bring me something in trade (a cutoff bit, a 24V machine lamp, or ??), or provide me with a good story as to why you want it - the best offer or story wins - if no one wins, I'll use it as a roll around air storage tank and throw the compressor away. This thing is located on the west side of Los Angeles.
