Lee, I'm back on the phone now.
The only thing that goes against this theory is that the top coat has peeled away in places and left the undercoat Free to tarnish, it looks very much like paint on paint. I'll dig some pics out. Id it was a wash coat I doubt it could peel/flake away in the same manner. All the wash coat damage I've seen on the B wing Red 3 etc has a very different way of acting and usually its the layer beneath that peels away. I am with you though.
