Definitely a Caille 5 Speed, and a great find. I believe the recoil starter was introduced around 1915, so without checking serial number etc, your Caille would have been built between 1915 and 1924.
More details here: Caille Index
As a side, I have a friend over here in Australia that is working on one right now. His recoil starter is however damaged internally. Will need to fabricate many new parts to get it operational again.
