Pathe-Magazine Revue Universelle des Sciences, Arts, Industries, Voyages, & Sports, No. 38

Approximately 1 1/2 minutes into this newsreel, there is a segment on the building of an automaton. The title frames are held for a long time but you can stop the film to see the actual work on the figure.

Title frames transcribed for that section:
The Art of Mechanics. Automated Mannequins. The body of the mannequin is first modeled by the artist then molded in a plaster mold. A complicated mechanism gives the impression of life. The anatomy of the smoker. The machine produces smoke. A perfected subject.
