Appleseed/Appleseed Ex Machina Firearms

I agree that they are cool but even if they are fictional, how come there's a Seburo Firearms page? Both GITS and the Appleseed series use Seburo weapons (since they're both made by Masamune Shirow). There also seems to be real guns in Ex Machina. Deunan's sidearm sorta looks like a USP or MK23 and that in some pics, Briareos is holding what looks like a G36 variant. I'm just saying that the Appleseed guns should at least be shown in their own fictional firearms page or in the Seburo page.
