What Physgun Skin is this?

Sorry if this is the wrong place to do this. I am new on Facepunch. I found a physgun skin on a youtube video and have no idea what it is called. I have a photo of it, if that can help. http://i.imgur.com/2WgNCmV.png?1
That is the only source I have on this addon. I have seen it on some popular youtube videos.

Just saying, if you guys think this is in the wrong thread (moderators and admins and any other staff), please move it. I don’t know where to place it. Sorry.

here you go fam

Thank you very much sir. This is appreciated.
