Some resemblances to the original model ...

The Iron Man version with the head embedded in the robot's back...

The Igor version with head wrapping the mask of Iron Man, the seat of the pilot comes to fill in the back of the robot the empty space corresponding to the head of Igor ...

When the upper body is opened from the front, it does appear the pilot who is fixed in a sitting position on this torso ( on the last pic)...

The Mark 38 (XXXVIII), or otherwise known by it's name as the "Igor", is a Heavy Lifting Suit, and was one of the many newly built suits created by Tony Stark, sometime after the events of The Avengers.
It was featured in the movie Iron Man 3, and made it's debut in the movie when Tony ordered J.A.R.V.I.S. to initiate the "House Party Protocol", in which it was activated along with all the other suits to aid Tony in his battle against Aldrich Killian.
The suit earned it's name the Igor, beacuse it has a similar resemblance to a hunchback, having a slouched and bulky appearance, just like that of an "Igor". It specializes in lifting heavy objects such as debris, and is capable of tremendous strength and power.
Having an Enhanced Multiple-layered Titanium Plating, It's armor is the thickest of all armored Mark suits, making it the biggest suit of all, as well as the strongest in physical strength and durability.
The Mark 38 brings a whole new design into the various types of armors in the Iron Legion.
The Mark 38 has two stabilisers on its legs, to assist lifting extremely heavy items such as the docks as shown in Iron Man 3.
The Mark 38 has standard heavy duty repulsors, used to help lift up the suit from it's very heavy weight. It is not used for combat, and is only used when the suit flies.
This suit is seen smashing through crates and stabilizing the docks when Tony tells Jarvis to stabilize the docks after the Mark 31 crashes into a pole making the docks unstable.
