Singularity TMD - need reference pics

[Phaestoz]

So, I'm on my second play through of the game Singularity and I've decided to try to make a replica of the TMD. Unfortunately the best reference picture I have slightly angled in all the views so it's not the best and I am still pretty new to prop making. I started drawing up some rough scaled drawings but I'm unsure on how to get the curve of the base piece that lays against your arm.

I also found a version the model from the game as a .mesh file but I have no clue how to do anything with it. If anyone has any other reference pictures that would help I'd love to see them.
