Outer Limits 4x4 Board

I've got a rover V8 manifold with a Holley carby on it, the carby just has "Redline" marked on it, and a whole stack of "covered by part numbers..." listed.

Is this manifold + carby worth anything?

Put it on ebay 4 barrel manifolds to suit 3.5's are worth a little, last one I had years ago I sold to RangieAutomotive
