From the Seller's Description:
"The main figure of a man is articulated on his right side, at the shoulder, elbow and wrist. He is articulated on the left side at only the shoulder and elbow. He is whittling a piece of wood with a real metal knife. I believe he originally paused and lifted the object to examine it, then continued. He may have first had a clockwork movement but when I received it, someone had attempted to operate him with an old clock motor and an old porcelain electrical on off switch appearing to be from the very early 1900's."
The seller is offering the piece with many parts, a curved glass front, and a gear motor to power the automaton.
