Here are five more examples of Philidor's Legacy from actual games. I'm not sure whether this maneuver can be considered an actual trap, but it's certainly trappy in nature and the potential for an opponent to use this maneuver can be a tactical weapon in itself.
The first three games were conducted by Paul Morphy and one of those an "odds" game. The fourth was played by Franklin Knowles Young, one of the Mandarins of the Yellow Button and the final example was from a game between the great John Cochrane and the almost great Indian player Mohishunder Bannerjee.

Following the clever suggestion by member normajeanyates, to hopefully circumvent some of the game-loading problems, I've placed the pgn below each of the games.
