A picture of the box it came in after the break.
Answer from Federico: “It’s a ‘feet action rear derailleur’, as you can read in the pic showing the box. Pushing the right feet on the triple-leverage, the pulley moves a step left on the bigger cog. A push, a cog, till the pulley shifts back again on the little cog.”
