Hopefully someone can help me here. I have had this Sard Type RJ Regulator for years, and was looking at using it on my car. I've seen alot of stuff about real and fake ones online, but nothing seems to match up with what I have. I'm hoping someone can tell me, or point me in the right direction to work out if its real or fake.

 

Well, for what it's worth, I have a fake one.

And it doesn't look like that.

My top is blue, sticker doesn't have Japan on it.

 

Thanks
