Cuckoo Clock Thorens Movement Switzerland

Cuckoo Clock Thorens Movement Switzerland. This clock is untested, mainly because I know very little about these types of clocks. All 3 weights are present as well as pendulum. It has double doors, the right one is the Cuckoo bird, and the left is a little man. The right door is not attached but present, and since I don't know too much about them, I'll let the new owner take care of it. The bellows are fine and I tested them by lifting the arm, they make the noise required. I'm selling this as for restoration or repair because I don't know how to test it.
