Lego Commando Droid original or fake Legs I have some LEGO Commando Droids. The torso, head and arms are original with the LEGO logo, but the legs have no logo. They do however have numbers on them (here 2, on others 4 or 3) The legs are in terms of form and material identical to the original legs.
It seems unusual that somebody would go through the effort to fake the legs but not the rest of the droid.
It also not uncommon for official LEGO parts to exclude either a part ID or LEGO copyright stamp, this could be because the part was manufactured before it was the standard but most likely through design considerations.
It looks like there are no flat/continuous surfaces where either of these markings could be made legibly and without spoiling the characteristics of the part.
Looking at official set photos as well as reviews seems to prove that these parts are most likely real.
