C-3PO I CODE: sw010 SET/S: 7190, 7106, 4475, 4504 Who couldn't love this prim and proper protocol droid. I guess the 4cm minifig style suits this character more than any other, I love the head.   C-3PO II CODE: sw161 SET/S: 10144 This is the middle rare 3po and noticeably darker than the original, exactly the same apart from the colour - it's a shame they couldn't of matched the hands though. C-3PO UCS CODE: sw161a SET/S: 10188, 10198, 8092, 8129 He's almost complete, but there's still one thing wrong with this Lego character and maybe one day they'll get around to doing his silver leg... Or am I getting a little too fussy? K-3PO CODE: sw165 SET/S: 7666 This appeared in the Hoth play set. The two red dots on his torso indicate it was actually a lieutenant officer. Also as it appears in the Hoth set is actually wrong as it should have a damaged torso - isn't Wookiepedia great for filling empty spaces...   DEATHSTAR 3PO CODE: sw212 SET/S: 10188 Despite a few hours searching the net, I cannot find any reference to a black 3PO on the Death Star. The closest I got to it was an Assassin Droid, but that was a different droid series. R-3PO CODE: sw344 SET/S: 7879
