The female snake charmer automaton is "Zulma, La Charmeuse de Serpent", perhaps one of the most visually compelling automata to come out of the firm of Roullet et Decamps of Paris, produced by Gaston Decamps himself in 1907.
There are a few automata I've seen have this action. I believe the chest is a separate piece, most likely moved using billows, but I'm not too sure, she is a complex piece and I'd love to see how she works too.
