What can I say about the original fixed limbs C-3PO? It's one of the first 12 figures released for Star Wars... and it rocks!

I loved this figure as a kid and I love it still!
There are a surprising number of variants to be found on the fixed limbs C-3PO and I by no means have them all, but I do have a few to share, including a dull gold Lili Ledy/PBP figure complete with flat head screw in the centre of its back (PBP imported their C-3PO figures from Lili Ledy according to the excellent Variant Villain website, so they are effectively one and the same thing), a Japanese Takara C-3PO with its completely different body and head sculpts and a cross head screw in the centre of its back, plus a Palitoy 12 back.
I should also correct an error from the old Toy of the Week 1 C-3PO thread where I mistakenly believed the red gold Kader I, 1a figure below was a PBP one. That's how it was sold to me, however thanks to the Variant Villain website, I now know it to be Kader.
