I know they have one preserved in the museum in London, but I do not believe there are any flying Tempests, or Typhoon's for that matter.
And I don't know of anybody who static runs a Napier Sabre. More is the pity there, eh?
Only one complete Hawker Typhoon still survives - MN235 - and it is on display at the RAF Museum in Hendon, North London. It was previously on display at the Smithsonian Institute before being presented to the museum in comemmoration of the RAF's 50th anniversary in exchange for a Hawker Hurricane.
