This is the film L'arcieri di fuoco (1971) in HD with English dubbing. The English title is listed in different places as "The Archer of Fire", "The Scalawag Bunch", or "Long Live Robin Hood." This video is an amateur amalgamation of the HD video that I found online and the English version of the audio recorded from a VHS tape of "The Scalawag Bunch" (which is the only release of the film in English that I am aware of). The front and back of the VHS box may be seen here: https://www.samuelstokesmusic.com/The... (It incorrectly identifies Mark Damon as Robin Hood instead of Guiliano Gemma).
The film has some slightly different cuts between scenes, along with one 30 second horse-riding scene cut out of the English version at the beginning, so there are some spots where the audio switches between versions or drops out momentarily so that the audio remains in sync with the video. I decided to leave the HD video fully intact and only edit the audio as necessary. Hopefully, someday an HD version with better quality English audio will be released, but in the meantime, hopefully this will help more people to discover and enjoy this film that I very much enjoy.

If you have any further information on the history of this film, or the different home video releases, please leave me a message in the comments.
