Last night I was glancing through Cecil Clutton's book on the VSCC (Vintage Sports Car Club).
When it was formed (1954), it was going to be called the "Veterans" SCC, however the true Veteran's Club objected. Thus true veterans date to 1904: "Edwardians" are defined as from 1905 to 1916: and Vintage from 1919 to 1930.
As I think I mentioned previously, the VSCC used to have a class they termed PVTs (Post Vintage Thoroughbreds).
And to me, the term "Thoroughbred", sort of sums it all up!
I do agree with what you say about mags, these days; no doubt we'll soon see a publication called "Trabant Owner", or similar!
