Err... umm... I'm displaying 3PO with the bolt and my BD Luke Bespin is next to him posed as Bespin corridor...
It's the part circled here.
You lobbed...
It's the tip of one his "collar spike" thingies that is missing. It's only a little over 1mm missing, but it was broken out of the box.
I tried the generic HT stand that came with the muscle body and it just didn't feel secure. Also didn't like the painted metal of the loops pushing on the top of the inner legs. Every time I removed it it felt like it would scratch.
Yeah the included stand just doesn't feel safe. Not sure if a regular "old" SSC style goes high enough and if the ring is large enough to go over 3PO's head, but my stand is from one of the Diamond select Ultimate 1/4 figs and it has that same split ring. I just raise it to take 3PO off display, then put him back and lower it down over his head to his shoulder line. I put some clear tube on the ring so there's no metal-metal contact. You can't really notice it when in place and its just a black plastic disc as base (though larger than the SSC base.)
