423 FLD – where are you?

Hello all fans of Alvis, I’m sending you as an interesting photo of this car, which was taken accidentally in Pilsen (Czech Republic) in 1971.
Sincerely, Slavomir Altman, Pilsen
WHERE IS IT NOW?

This TD21 Series II bears a London registration which now appears on a 1965 Bristol 408 last mot’d in Kent. Does the Alvis survive?
