Need help - mystery-movie-stills!

I recently got 17 spagehtti-western-stills (all from the same movie), but unfortunately I´m unable to figure out the name of the movie! Maybe some one can help me out? Here are 4 examples:

Any ideas?

My guess is My Name is Mallory but I’m not sure.

Yes, Il mio nome è Mallory … “M” come morte.

Definitely looks like Mallory to me

YES! you´re all perfectly right! It´s MALLORY! Thank you VERY MUCH!
