Not Hasbro’s best design. Judging by the number of “incomplete” listings, and my own experience, these guys come apart pretty easily and they require an advanced degree to transform.
That said, here is a parts lot featuring some or most of 10 figures: about 55% of the Ahsoka Tano figure; maybe 35% of Darth Vader; two Obi Wans that are both pretty close to complete; two Chewbaccas, one about 40% there and the other looks pretty close to complete. There’s a Clone Trooper that I’m pretty sure is complete, the Han Solo half of the Millennium Falcon set that is missing, at a minimum, Han’s head. Some kind of droid with no arms and one accessory from one of the rebel fighter figures (that’s the orange bit.)
As you can probably tell I don’t know much about these — Transformers are really not my bag. But there’s a lot here and I’ve priced them cheap for someone who wants to tinker. See photos.
