From the Frank Nelson's web site:
"This is a one-off original automata. The two figures standing on a wooden carved fort. When the lever is pulled to the right the jointed Officer presents a medal. He leaps into the air – raising his head. The soldier turns his head, salutes, and receives a kiss on his right cheek. Pull the lever to the left and the opposite cheek is kissed."
