Need help with 3d model. (Halo 4)

I was wondering if anyone would be able to give me a hand. Im looking for reference of the covenant plasma grenade from halo 4. I assume its symmetrical in design, so all I require is a front and profile view of it. This is for a project I hoped to accomplish in blender.

All Ive been able to find is this File:H4-PlasmaGrenades.png - Halopedia, the Halo encyclopedia but the angle is off from what I would need to do this properly.

Thanks in advance.
