Which does not make it "rare" but "unique", two very different words meaning two very different conditions...
I agree about keeping certain objects intact as found, as they are indeed original only once, but others need physical "resurrection" help if they are to be preserved from disappearance from corrosion.
Slot cars offer us a bit of leeway because they are after all mechanical objects, and their resurrection is part of their continuing mechanical life. Like an old racing car that gets an engine rebuild so that it can still be used.
Interesting, in most areas of collecting restoration destroys value not enhances it. Is it a PVA chassis or a Steve Okeefe chassis now ??
Paul, with such a sympathetic restoration, it is absolutely the original PVA chassis since none of the major parts were replaced. It was mostly cleaned, its corrosion removed (blame Bob Emott's humid basement in NJ! ) and that's it. Even the lead weights on the side pans weren't touched, one of the benefits of using a tumbler to clean old chassis. In fact, let's face it, before that cleanup, the only non original part of the chassis was the accumulated dirt and grime on it!
