I just took a quick look on Ebay and didn't see anything like it.
I see why you picked him up. He looks really cool. I would've done the same thing. Without a tag to give us a name brand, tracking down info could be very hard. I will say that he doesn't look very old. I would say less than 10 years old. I might be able to tell you more if if I could see a better picture of him.
