[Can anyone identify this armor?]

I picked this up from someone last year and just recently had the time to start trimming it. I figured since it is somewhat yellowed, although sanding with fine sandpaper brings the white back out somewhat, I would make this my Sand Trooper, although it is missing some parts. But I cannot pin down which armor it is. It has ROTJ hand guards, and the Ad plate is odd,

 

Enough talking, pictures are what we need here:

 

OK, for some reason I cannot paste links to my photobucket.....

[Starting my ATA build!]

Hey all,

 

I have been lurking here for some time, but I got on ATA's wait list last October, and it should be here today!

 

I am actually an old inactive member from 2000! TK/TD369. I had a FX kit back then and loved it, but now I am seeing that are not the chosen suit anymore.

 

Anyway, cant wait to get it and get started, it has been a very long time coming
