I don't think it's a good representation of size. I looked but I think our other posts were collateral damage being deleted with the whole "$$$" pissing contest that went on. Arnold simply wasn't the same size in any of the other movies. He'd lost considerable mass between T1 and T2. He was a bit bigger in T3 than he was in T2, but not by much and was bigger in TS than T1 because that was Kickinger's body who's bigger than Arnold ever was. I think the "Dutch" proportions would be great for a T1 or TS T-800. The proportions used for Krauser's body would be more fitting for a T-2 T-800 and a T-850 for T3.
Do you have an image link for the Krauser body?
