American Rifleman had a review article about the Star "Progressive" in May 1934, so it was certainly commercial by that date. Clarence Peterson applied for the "Star" patent in July of 1933, and Patent 2,031,850 was granted on Feb 25th 1934.
The Star in the video has the Pat. Pending aluminum base, so it was most probably produced before May of 1934. The very earliest machines had cast iron bases. Slightly later they had the aluminum base, but had a brass powder slide housing which the machine in the video does not have.
I think it is safe to say that the LAPD was a very early adopter of the Star reloader.
