Tam really knows the business when it comes to a mind bending quizz. But with all due respect to his towering intellect, he has nothing on me. This could take some time to figure out. I am a knighted appendage who won the Epsom Derby in 2006.
This looks dodgy, Cyclonic,. Harry Hotspur might be the answer, but you're more devious than that! The clue must lie in "appendage," so it could be his jockey, Martin Dwyer; his saddle, etc. Or did you mean "a knight's appendage?" In which case I'll go for "armoured codpiece."
