Kino has just announced a 50th anniversary Blu-ray set with both the theatrical and extended cuts remastered in 4K, and both with the Italian audio as an option (would love it if they did the previous two “Dollars” films this way, too). Hopefully the “Restored Mono” means these are the original English mono mixes. No set street date yet, but TheDigitalBits thinks sometime this summer.
