A great job Robert! Nice to see a set like this restored so well, as you say a complete strip of the chassis was the only way forward after it had been daubed like that, it amazes me what some people call "refurbishment". I once saw a classic S type Jag that had a lovely job done on the engine but while it was out the owner had painted the whole engine bay with thick black hammerite!
You must have the patience of a saint!
