Plot hole: When Bond and Scaramanga are duelling, Bond has no tie or jacket on. After Bond drops his gun and gives his hiding place away, he somehow has the time to not only crawl back onto the staging but to move the wax replica of himself and also to put on the dummy's jacket and necktie.
Plot hole: Scaramanga kills his boss Hai Fat in cold blood inside Hai Fat's massive estate in Thailand, but even after Hai Fat's attache runs inside and sees Hai Fat dead, murdered by Scaramanga, the attache and Hai Fat's security personnel in the heavily guarded complex permit Scaramanga to leave without being apprehended for the murder of their boss with Scaramanga glibly stating "Mr Fat has just resigned. I'm the new chairman of the board" as he walks out of the room untouched. (01:04:50 - 01:05:25)
Answer: I haven't been able to find any information on its whereabouts so my guess would be that ended up like most movie props do. Either as a souvenir for one of the people attached to the movie, (actor, director, etc.) in storage (in case it could be recycled as a prop in another movie) or simply discarded when it wasn't needed anymore.
