After reading
Is the man with no name the same character?
and specifically, this answer, I began to wonder about precursors of the 'Man with no Name' character, played by Clint Eastwood in the epoynmous trilogy of Sergio Leone's films (The Good, the Bad and the Ugly; A Fistfull of Dollars; For a Few Dollars More).
Are there similar characters in earlier Leone films, or in earlier Spaghetti-western(-like) films which inspired Eastwood's character or which could be said to have 'developed' into it?
