So I picked up a loose Rattrap in an eBay lot a few years back that was missing the gun barrel piece. After lots of fruitless searching, I finally found a dealer that had the barrel at Botcon this weekend. When I got home and pulled out Rattrap's gun handle and slid the barrel in, it was a very loose, wobbly fit. I thought, "Maybe one of these is a KO", so I pulled out my Big Lots KO Rattrap, but the KO gun was visibly different from the "official" gun I now own. I tried to see if the gun pieces fit into his rat "shells", and sure enough they fit in perfectly. Also, the gun handle piece fits the fist hole perfectly. I did some investigating online... Fred's Variations has no listing for any variations on Rattrap. I searched Transformersland, which has large, clear pictures of TF parts, and found their pics of Rattrap's gun pieces. My pieces look virtually identical to what TFL has pictured, right down to the injection points. I included a picture of them below (from two different angles), and I highlighted the "problem" areas. Anyone know of any Rattrap weapon variations? And is there anyone with a complete Rattrap that can look at this picture and tell me if one of the pieces is a KO (and if so which one)?
