I disagree with the "perfect the way it is" statement re: the HT Mk I. Besides the sculpt issue, the entire surface finish isn't right. The HT Mk I is a very dull silver, and heavily pitted/weathered looking. The actual movie suit was FAR cleaner/shinier looking. Yes, the suit was improvised, but the base materials were mostly new munitions and parts, not scrapyard junk. Witness:
Honestly the original HT Mk1 surface condition looks more like after the fight and crash when it's been pieced back together.
HT is bragging on the special steel like finish on the Iron Monger, could be applying a more realistic finish for the Mk I may be part of the reason for the revisit (that and raking in an *$$load of cash anyway...)
