Show & Tell: Diamond Dogs Arm - Dub'ya Makes

Just a quick one, to show off my latest flea market find... Contrary to what I muse about in the video, I think this may actually be some sort of Metal Gear swag - one of the texts on it says "Diamond Dogs R&D Artificial Limbs Laboratory", and MG is the only thing that comes up when throwing that into Google. I've never played it so I can't tell if the style fits MG aesthetics or whatever. Feel free to enlighten us in the comments if you know anything :) Bonus link: If you didn't know about "The Invisible Orange", now you do - https://www.urbandictionary.com/define.php?term=invisible%20orange
