What gun scopes correlate to their Manufacturer?

I've been tweaking with Gibbed's BL2 Save editor for a bit now, and I'm having a little trouble with one aspect, gun scopes.

In the editor you can create guns using whatever parts you want in that. THe problem is, you can't preview it, so if you want to see what the scope looks like, you'll have to edit via Gibbed's, Open BL2, find gun, screenshot, then close BL2 and run Gibbed's again.

Basically, if you could provide pictures detailing the scopes for the six weapon types, SMG, Pistol, Sniper Rifles, Assault Rifles, Shotguns, and Launchers with their corresponding manufacture's, that'd be great!
