Earp of the Old West (5)
I believe the answer is:
wyatt
'earp of the old west' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for wyatt that I've seen before include "& 9 Across US frontiersman" , "-- Earp, US frontier marshal" , "-- Earp, US lawman" , "Sir Thomas -, sixteenth century English poet and diplomat" .)
