At little info on them for you - the 1909 first shows up on a loose insert page for catalog #24 - page 16B, and is no longer listed in catalog #50, which I think is the first to have the "NEW 22 SAVAGE AUTOMATIC RIFLE" model 1912. This suggests a production run of less than 4 years.

Here is an early brochure -
