FOR SALE Magnum exhaust manifold

Will be replacing my stock exhaust manifold with headers, my car is not a numbers matching vehicle so not too concerned on this. But mechanic mentioned that my manifold did not match the 383 that's in my car, said this may interest someone who is trying to build a matching numbers vehicle.
He mentioned you may get a fairly decent price on this since its original and has the factory markings.
Any suggestions would be help full.

Pics would help....
