I just bought what I believe to be a very clean and original and fully operating Tireflator. I've been looking for one of these for my garage as I've always thought they were really cool. The best I can tell it looks to be original paint because the nicks and scratches it has show the paint thickness is not thick, looks to be only painted once. I've never seen a black one so I'm not sure though. I would like an opinion on if it's original and what model it might actually be along with an estimated date. The tag is not on the back. Inside the cover appears to be original or atleast not aftermarket. I think I would like to know a guestimate value to see how much I over payed LOL
