The type of collector who'd be after this one would most likely prefer he not have it "fixed" (so as to not risk getting it messed up, made non-original, etc.). They'll want to handle the restoration themselves (or arrange for it themselves).

Cosmetic condition is king, so without pictures, it's hard say value-wise, other than it's generally very valuable (certainly more than that offer).
