Sorry for the late reply. It is a working model for sale. From the seller, the AF function actually works. As I know, EOS mount has 5V power supply which will power the electric motor.
PS. the black box underneath is probably the controller PCB taken from a working lens, thiat will be used for communication to camera body. Before USM was invented, convention electric motor was served for AF. So, it is poosible to add a motor to the contoller, so that it will drive the focus ring by the camera.
