original RS bumper needing work whats it worth

[carrera turbo]

ok guys im pretty sure now after talking with a couple guys that this bumper is real. what im trying to decide is if i should pass it along to someone, my plans have been to run it on a rs clone but i really dont need a real bumper to do this. this bumper needs some glass work but is very much fixable. i originally thought there was metal in this bumper but did the magnet test and was assured by someone else that saw the pics that it was just staining from the deco hardware,and they where right. i am going to repair the damage and prep it for paint. any help on what this is worth as i may sell it to help fund my early car build. i started a thread in the tech section on helping identify this bumper and im sure the metal over glass had everyone thinking i was nuts.

cheers ed
