Prints of the sound and silent versions of this film survives in the UCLA Film and Television Archives.
The "sound" version that survives is actually the work print for foreign language releases, never intended to be seen publicly. It's basically a silent film made from the talkie, with the titles only presented as what to translate, and how many frames to hold to accommodate the sound track, which will contain all non-speaking parts. Those parts are more or less the synchronized sound effects and music edited to make it sound like an early vita phone/movie tone scored silent.
The most remote post office in the United States was discovered by the Fox company making the Lone Star Ranger. Kayenta, 175 miles from the nearest railroad station, has as its postmaster an old miner, whose post-office comprises four compartments in an old soap box. While the motion picture company was shooting in that vicinity, the postmaster did a flourishing business in outgoing mail, which was transferred to Flagstaff once a week on horseback.
