Help identifying soundtrack

Hello. Requesting help from you in identifying a piece from a movie soundtrack that appears in a 1977 martial arts film, however I’m 100% sure this music was not composed specifically for that movie but rather stolen from another film. I personally think the sound resembles a spaghetti western film and was wondering if you could have a listen to a sound file I recorded from the movie and let me know if you can identify it for me? I have wondered about this music for over 30 years.
Hope someone can help. Thanks for reading. Download link for the mp3 file:

Sounds like Nico Fidenco, but I don’ t know for sure and From which soundtrack that is…
