Below you see three Rebel Commando figures. They all have the China COO, and share the same mould. The main difference is the moulded face (left) vs the painted face (middle and right). Rebel Commando China: Moulded face (left), Painted face (middle and right).
There is however another small difference when comparing the middle figure to the other two. Can you guess it?
Scroll over with your mouse to see the answer below.ANSWER: THE MIDDLE REBEL COMMANDO LOST THE BUTTON OF HIS SMALL BELT POUCH.
Probably a small deformation which happened during production.
