The ARC-170, physically, reminds me of an Avenger Torpedo Bomber...  That's just physically though.  It's a light bomber/torpedo plane that saw a lot of use in the Pacific.  Also 21st made a 1:18 one of these, their largest plane they ever did IIRC.  I have one, hanging from the ceiling, and it's about the overall size of the new Millenium Falcon if not a bit wider. 

The ARC-170 could also be compared to the German Junkers Stuka Divebomber which was another prominent plane in WW2, especially the earlier years of the war.  Also a 1:18 plane 21st made.

The Avenger plane they made is just insane.  It was $75 originally and kind of uncommon.  Ironically I got mine half off because WM never put them out before Christmas, and just blew them out then.  Very dumb considering how uncommon they were.  Here is one deco of it:



There's a crew of 3 and it came with all 3 figures to boot...  Very cool.  The wings folded for storage on the carrier, and so does the toy.  The torpedo/bomb bay opens and has a removable torpedo...  It's sick, really.

I agree, not to derail the topic, but it is fun to look at the real-world counterpart to the inspiration of many of the ships from Star Wars...  From a customizing standpoint I love to draw parallels between real-world armor/vehicles into Star Wars vehicles.  It's the trademark that, to me, makes Star Wars models unique and interesting.  There was a bit of that lost in the prequals at first that Lucas got back to in the latter films.  E1 lacked it tremendously though, going with more a classic car look...  I didn't care for that as much. 

When will we see a new Zam Wesell figure? A resculpt seems long overdue, and it's been seven years since we last saw her in the basic figure line.
