Shame it's not a Tempest V.
How is it a shame? The V's had a different Engine that I've heard are difficult to restore.
I've seen a Napier Sabre in a Museum & it sure looked complicated.
You've kinda justified Doug's point in your own post!

It's a shame because the Tempest II is reasonably similar to the reasonable plentiful Sea Fury. I'd be excited by an airworthy Tempest II and it Centaurus, but due to the rarity of Hawker Typhoons (1!) and Tempests Vs I'd love to hear the (somewhat utterly mental) sound of an airworthy Napier Sabre!
Old recording, but have listen. Somewhere between a Merlin and a Pulse jet. A bit like the aeroplane equivalent of BRM's V16 F1 car of the 50s!
