The Rolls Royce Merlin Engine: Not from a TVR, and not for one either - just an interesting photo. I spotted this engine at the 2003 Biggin Hill air display, and it was recovered from a wrecked Lancaster Bomber in France. Note the damaged right rocker cover showing the shape of the actual rockers underneath!
