Halo Reach Markings

Hi guys,

A little help here if you would be so kind.
I'm building an MA37 for a commission, I'm working off two excellent images of 3D concept art for the paint scheme.



I'm trying to find images of the emblems so I can cut stencils for them. The 'UNSC' is easy to do, but what about the black marking on the scope central section? It looks like a stylised 'P' with 5?20 behind it, or the subtle grey marking in front of the cocking lever?

Could it be an eagle? Or a skull with wings? I can't make it out.

I'm sure there's a post or a thread for all this stuff somewhere, but I couldn't find it.

Juliet76 has a lot of reference shots in his Photobucket: http://s1041.photobucket.com/albums/b412/juliet76_405th/MA37 ICWS/

Here's a better view of the front marking:

Looks like a squared off, stylized "P' like you said, and 5i20.

The markings near the middle look like the UNSC logo, and "-??- Armory". I would guess Misriah Armory, since that's where the Magnum is manufactured.

Thanks guys, I think I have them all now.
