Is this a pre-production figure or a KO?

I've been buying Transformers, from an eBay seller in China, and the items all have appeared to not be KOs (some of them in the "Why would anyone bother to knock something this cheap off?" price-range).
I bought some First Edition TF Prime Bulkheads from this seller, and one of them has uncolored limb joints (like the ones on Xovergen's Supreme Tactical Commander) and the number "103" printed on the front of his chin plate.
I'm just trying to figure out what I have here ... (I just took a pic of the upper part of the torso, but the joint coloration applies to the other joints as well. Also, the body color isn't different; my flash just went off on one and not the other).
