Only because I never got an SDS chestbox. Timing-wise IIRC he did the TIE helmet after the Stormtrooper helmet. Then LFL got "involved" so I backed away.
I'd already bought a laws helmet, armor and chestbox combo from Dan so I put the SDS helmet with the laws chestbox and armor as I thought it worked better.
It was after that AA did the Stormtrooper armor and then the TIE chestbox and armor some time after that.
Accuracy-wise I think the SDS chest box casting is good and probably a cast off an original, however it looks to me like he's flipped it front to back (ie its the wrong way round). He's also added the coffee cup holders on the top which werent part of the original casting but may have been "o" rings or something similar added to them after (or some of them or the prototype). Its hard to say whether ALL the chest boxes were "flipped", since only 1 chest box seems to have survivided, which is currently in the LFL archives, but that is certainly a different way round to Ainsworths.
Hope that makes sense!
Cheers
