Built in Tales of Suspence #40, Golden Armor, Model 1,Mark 2.
Most changes were cosmetic. It was constructed out of lightweight iron alloy, and gold plated for force field experiments and to give him a better image as Stark's bodyguard. Tony added a kilt on the armor, and made other adjustments for a better, and more streamlined look. But it's functions, and links were like the original armor. To help Stark keep his alternate a appearance secret, Mark 2 was built flexible enough to collapse into a secret breifcase compartment, allowing for a quick change of outfits. The chestplate had to be worn at all times to keep Stark alive, so he slimed it down so it could be worn under his shirt.

      New Features: New boot jets capable of actual flight, jet powered rollerskates, and a spotlight in the chestplate. Improved communications equipment in the form of a telescoping antenna was added also.

      Weapons: Chest-mounted proton beam (7 yd. range) Early repulsor (based on reverse magnetism.)
