Kerry, yes a bit of trick question. What I got from Ken Hill a few years back is that (as you see in your notes) 600 and 500 are the same car, the Avon Coupe. H. St Leger Skinner is HFS' son in law. Married Stella, Peter's sister. It was given (supposedly as a wedding gift) or sold to them as used to get it off the books, off inventory, in effect a tax dodge. I have a photo of Stella circa 1939 sitting beside the Coupe.
Cheers,
