Typical out-of-sequence shooting; holes were made by Mortimer in the street "duel" than sewn up for closer takes or re-shoots.Similar to the sewn-up bullet holes in the poncho from Ramon's bullets being visible earlier in the film, where Eastwood or continuity person failed to reverse the poncho to hide the sewn holes from the camera. In a few scenes in FDM and GBU the sewn-up holes in the poncho can be seen.
I guess it was a one-of-a-kind poncho they could not find another one for FAFDM!
Poncho, vest, and hat were one of a kind items. Eastwood took his outfit back to the hotel with him every night, didn't trust the Italian crew. He told same to Van Cleef and Wallach, and also told them to write down what they'd said, to make sure they'd get it right during dubbing.Clint has the poncho and other stuff (including the rattlesnake handle revolvers that he'd purchased after outlaw used them in Rawhide episode 3). These were all on display at the Leone Exhibition in Los Angeles 2005-2006, I saw them there. Clint wore the poncho in a parade a few years ago, see the holes.
I also believe that the poncho was picked up in Europe.
I never really believed the Eastwood story. Something that is so Leonian and so not Eastwoodian had to be at least discussed by Leone and his team. Also Leone said (in the Simsolo book?) he didn't like how Eastwood was dressed (irl not on screen). My bet is that Eastwood came with some parts of the costume but not everything, and not everything was greenlighted.
Clint Eastwood received a copy of the script, presumably with the working title "The Magnificent Stranger" (Texas Joe). The poncho is mentioned in the script. Thus, he would have known in advance that it was going to be part of his wardrobe. Carlo Simi, costumer designer, would also have known that the script described a poncho and, at some point, he made a design sketch of the poncho. The screen used poncho was very similar to the design in the sketch, but it included some more elaborate patterns. Thus, the screen used poncho appears to have emerged from the production "design". In other words, the Simi sketch was not simply a portrait of Clint Eastwood in a purchased poncho.
